the common coordination atoms are non-metallic atoms with large electronegativity. Most of the formation bodies of NOSC halogen (fclbri)
should be transition metals. It seems that trivalent iron, bivalent copper, CO + and univalent silver ions can also be. Remember there's a (BF4) - it's a whole< The transition metal Ni is a common central atom in the textbook, (Ni (CO) 4)
Ag + + 2nh3 = (h3n-ag-nh3) +
in the ligands, I have monodentate ligands and polydentate ligands. The polydentate ligands don't matter. The monodentate ligands have neutral molecular ligands such as H2O, NH3
Co, CH3NH2. The anionic ligands include f-cl-br-i-oh - and the cationic ligands cn-no2-ono, Your teacher should have talked about the large (PAI) bond), scn-ncs -
remember that the coordination atoms are electronegative atoms, so the ability to attract electrons is strong, it is possible to form complexes
the coordination number of the central atom is related to the charge and radius of the atom itself. The larger the radius is in the small range, the larger the coordination number is, The coordination number of Cu + Cu2 +: 2.4
Ag +: 2
au2 +: 2.4
Cu2 +: 4.6
Zn2 +: 4.6
Cd2 +: 4.6
pT2 +: 4
Hg2 +: 2.4
Ni +: 4.6
CO +: 4.6
Fe3 +: 6
Cr3 +: 6
CO3 +, SC3 +: the same as above
Au3 +: 4
Al3 +: 4.6
pT4 +: 6
the ligand concentration should be appropriate, Temperature is also an index, generally low temperature and high concentration form high coordination complex
on the extension of the fourth problem: ligand field strength:
from weak to strong: I -, Br -, S2 -, SCN -, Cl -, NO3 -, F -, oh -, Ono -, C2O42 -, H2O, NCS -, EDTA (common in calibration experiments), en (ethylenediamine), NO2 -, CN -, Co. When we do this, we analyze the polarity of the material. Hooh and OO are a large PAH bond, which is not a non-polar molecule (H)_ OO_ The H bond angle is not 180). So you know, when we do it, we regard it as CO, which is actually a little more polar than Co, but it's far less stable than Co, CN - and many times OO appears as an oxidant, so it's not common in complexes. Coordination chemistry is the basis of analytical chemistry. Isn't it a bit BT for you to compete? Nowadays, children are so terrified. In fact, you spent two months to read books earlier, and what we have learned for three years will be compared by you. Come on
and give me a score. Although I didn't tell you the answer directly, I think what I described should be enough for you to deal with the competition
if you've studied hybridization, I think it's necessary to spend two hours looking at more than ten pages. To be fair, my grades are very poor, but I think inorganic chemistry is more interesting, that is, hybrid orbitals and molecular orbitals
shit, I only see the following things after typing these. Now the question is: do you want answers or principles.
Today's topic:
Why do Shanghainese not want to say they are Shanghainese in Beijing
How dare Beijingers say they are Beijingers in Shanghai
yesterday, I wrote an article" why is Shanghai more beautiful than Beijing, but I am willing to stay in Beijing for 10 years? "
many people jump out to stand in line for their hometown,
which city do you like best, Beijing, Shanghai and Guangzhou
make up for the next part today
In the regional prejudice of the north, Shanghainese are hypocritical, snobbish, materialistic and net red faced. We can understand it, but we don't carry itone spring, we filmed in a model house in a villa in Shunyi, Beijing. It was so cold that everyone was shivering
During the lunch break, everyone got together to smokewhen I answered my home phone on the balcony, Lu Yi whispered behind me:
I said that you are wrong everywhere. When you speak Shanghainese, everything is right
Pooh, everyone laughed. The hairstylist said,
yo, you are from Shanghai, I have known you for so many years, I really don't know=“ https://iknow-pic.cdn.bcebos.com/72f082025aafa40f8a91de15a064034f79f019a6 ">
for 10 years in Beijing, I have never deliberately disguised that I came from Shanghai
But to tell you the truth, sometimes even I forgetwhen I was young, I seldom spoke Shanghainese at home, let alone when I came to Beijing, even when I was studying in Wang Anyi's home. Mingming's sisters were all Shanghainese, so it was a strange experience to study in Shanghainese
the beauty of Shanghainese lies in a word of anger. In my impression, it is euphemistic and crisp. My most recent memory is Wu Ma in the history of the demise of romantic. She is neither humble nor overbearing, not affectable and beautiful
love scene of northerners
bullets pierce the heart without tears
between squares in Shanghai
there is a kind of bearing of Shanghai people, even the posture is more important than the result, no matter what happens, it will not show the color of haste
this is what Shanghainese call "eating face". No matter what you do, "eating face" should be good-looking
no matter what the family background is, when you go out, the dining table is "green with mountains and rivers" and the clothes are "green with mountains and rivers"
Shanghai little girl, even if her home is so small that she has to remove the door panel to sleep in bed at night, she is also a Shanghai version of Tang Yan, who never loses from head to toe
in social circles, it is not easy for northerners to recognize a group of Shanghai girls at a glance, who have a rich family and who have a poor family
taste has nothing to do with money. They eat, drink and dress up frugally. Since childhood, they have been taught how to make a dojo in the shell of a snail and always have the ability to dress up respectably
it's a gift. They know how to develop infinity from the limitation when they are young
Shanghai is a city with a strong sense of form. If any seed is thrown down, it will quickly ferment and spread, and quickly weave into a large precise net. There are many possibilities and connections between people
just like the beauty of the Suzhou style garden, the place is not big, but the winding path leads to seclusion, and various emotions interweave, fermenting countless possibilities. The slightest spark will ignite you. There is no trivial matter in the workplace, and you don't feel tired after a long battle
Mianli zangzhen is the most appropriate description. The thin blade slips past, and there is not a drop of blood
that's why large foreign companies have settled down in Shanghai for a while, and the value of executives from Hong Kong, Macao and Taiwan is very high
it doesn't work in the north where the cards are not played according to the principle
the degree of professionalization of the new youth in Shanghai is generally very high, and the top students are a golden road for professional managers after graation
however, the young people in Shanghai have not found a brave choice in the brutal war
at the end of the play, Rufei didn't leave, saying:
I can't leave, Rufei left the Forbidden City, nothing
there is a specific relationship between man and city
when the city becomes larger, opportunities are more than people, time is more valuable than money, and there is no close squeeze relationship between people, the whole relationship changes
if you think about the world, the pattern and the people, you will know whether this city is suitable for you
butterflies can't fly in the sea, and people have to choose the right battlefield.
just the same, not everyone can fight in the magnificent battlefield of Shanghai beach
after staying in Beijing for a long time, my heart will graally become almost transparent and become frosty. The past is like a breeze, leaving only what I want to leave
everything is simple and rough, and time is like sandpaper, which makes everyone heartless, simple and happy
to be fair,
Shanghai
is the city that knows how to cherish women most
the battle between Rome and Milan is as endless as the battle to the north
I've been in Beijing for 11 years, and I've enjoyed a lot as a girl. Naturally, I've been taken care of, treated well, and protected inside and outside
however, there is a strong logic behind this kind of "good to you" that is:
you are a woman
this stem has been a problem that I have been unable to overcome for many years
No matter how excellent your performance is or how hard you work, in the end, they still say:you are a woman, just be happy and beautiful
lovely girl, never short of love
but in the eyes of the overbearing president, you are a marisue
when you are coquettish, someone hurts, when you are sick, someone loves you, when you are heartbroken, someone accompanies you.
when you are passionate and say that you want to go to heaven and go to sea to do business, people who love you smile
for straight male cancer, the setting of women's social roles is just the icing on the cake side dish
today, Wang Xiaosha left a message at the bottom of my circle of friends, saying: 1 Beijing, 2 women's 3 families have houses, VC do not invest, do not believe that they can start a business
tagging is really annoying. I feel deeply about it. I wrote an article "ha ha," women are good-looking and don't work hard. "
what age is it? Hard work has long been out of date. Blooming is popular in the new era
straight men have a mindset that women can sell flowers, clothes and restaurants. They are good at beauty, taste and delicacy
But if you want to do what a man should do, you are not a womantherefore, in their eyes, Dong Mingzhu is not a woman who walks with wind and has no grass
only Shanghai has given us a lot of goodwill. It's not that Shanghai cares more about girls, but that it has given women a lot of respect and listening, real opportunities of equality and openness
Shanghai has given girls great patience and tolerance, and they won't be rude to interrupt or prejudiced just because you are a girl
the cultural and creative atmosphere in Shanghai is very nurturing. It's really hard to give enough room for girls to grow up and be well intentioned
no matter how crazy the idea is, in Shanghai, the attitude of being listened to is serious and sincere, not the look of smiling at you
this is also why Shanghai is the city with the highest status of women. In the traditional Shanghai family, women are the head of the family, and it is women who are responsible for their face
just like the Fendi's daughter, we Roman women want to be masters of the house. In the hallway of the house, there are pictures of grandmothers, not grandfathers
I have deep feelings for Beijing. Choosing Beijing is an important step in my life. If I choose the right battlefield, I will find the right direction to take off
after living in Beijing for 11 years, Shanghai still respects business rules most and values women's independent personality most
my little friend said:
"I told my parents that my boss is a Shanghainese, and they were scared. They said come back soon, Shanghainese are very bad"
I said lazily:
"your boss is very bad, not bad enough, you come all the way to me?"
smile
In the days of Beijing and Shanghai,in the clouds, you march forward in a whirlwind,
in a dream, you run things silently
torrent bravely into Beijing, Shanghai and Guangzhou
tangle and retreat back to your hometown
all the roads are your own choice
choose what you love
love what you choose
yesterday, there are thousands of backstage messages that can't be released, sorted by time, Post the latest
latest comments:
XM. Wang
11 years ago? The year when you left Shanghai was the year when I went to work in Shanghai. I didn't know why I chose Shanghai office between Beijing and Shanghai office. At that time, it was the talent introction of Shanghai. I work at the same time. Now I'm much worse than you. Ha ha. Although the heart is not willing to own choice, but never regret

what bloggers wrote is absolute and reasonable. We look at people and things, learn more, see more rationality and reason. Some people don't look at a word, just like being trampled on the tail, jump up and shout values[ Smile] learn more from bloggers and don't hold on to details

I came from a poor family and lived in Kunming, a poor mountainous area. In 2016, I stayed in the West 2nd Ring Road of Beijing for a year. I just felt that northerners were a little rough. But it's very bright. I still love Kunming, clean, forever °

as a Beijinger who just came back from Shanghai last month, I feel that I have too much say. In Shanghai, I don't look good. I'm too embarrassed to go out without a haircut. My little sisters are so beautiful and exquisite on the street. But in Beijing, I think how comfortable how to come, no one will pay attention to you, we only focus on their own lives. What's more, all the buildings in Shanghai are beautiful! The subway and the road are not congested in Beijing. It's really a good city to enjoy. But if you let me choose, I still like to live in Beijing. I think everyone is very close to each other. I especially like to find a tavern between friends or brag at the kebab stand. I feel that many men on the Shanghai subway will stare at the beautiful little sister all the time, especially? Although Beijing is abnormal, I don't think it's my illusion to cover my face so much.

in my eyes, Beijing is the city with unlimited tolerance described by Lin Yutang. Lin Yutang said that no nation is wiser than the Chinese nation. After that, after death, they conquered us. It was better to say that after a hundred years, our nation assimilated the people of the Qing Dynasty and absorbed their essence. And Beijing is

there are great differences between western modern urban planning and traditional urban planning (whether it is western or ancient urban planning in China), The western modern urban planning can not be regarded as the continuation of the western traditional planning, but developed from the new foundation, which is the core concept mentioned below
China's modern urban planning is formed and improved on the basis of learning from western modern urban planning. While introcing and learning from the western modern urban planning, the contemporary urban planning of our country also integrates the factors of our traditional urban planning and its system, and some contents of the western traditional urban planning. Therefore, China's contemporary urban planning is closely related to western urban planning, but also has its own characteristics
1. The concept and method of scientific rationality
scientific rationality is the foundation and core value of the whole modern society, and any discipline and social practice must be built on this basis before it can exist and develop. Modern urban planning is no exception. Modern urban planning is not only the case when rational functionalism dominates, but also in the previous stage when social reform is the ideal. They are all aimed at the urban problems existing in the instrial cities at that time, with a very clear problem orientation, and rationally designed countermeasures with the goal of solving problems; At the same time, it emphasizes the process of planning from investigation to prediction, which becomes the basic planning process; We pay attention to the application of science and technology, from the initial municipal engineering, to the pursuit of functional rationality and the emphasis on transportation technology, and then to the later urban research, the discussion of urban planning methods and the application of new technology in urban planning. Rational attitude, pursuit of rationality and scientific spirit run through the whole development process of modern urban planning very clearly. To a certain extent, the application of scientific and technological methods and continuous improvement of planning methods are always the pursuit of urban planning development
the concept of scientific rationality has spread along with the transformation from traditional society to modern society in China (i.e. the new culture movement represented by the May 4th Movement), which has influenced and regulated the development of all disciplines. In modern China, western modern urban planning was introced to meet the needs of rational (or modern) urban management. In the initial period, by employing foreign experts as consultants and being presided over by returned scholars studying in Europe and America, some urban planning work was carried out. In some concession cities, the planning work is carried out entirely by foreign experts in accordance with the basic system of their home countries. In other words, the basic factors of modern western urban planning were brought into China in the process of continuous introction of planning practice, and were implemented and magnified in the practice and professional ecation since then. Since the reform and development, in view of the tradition of China's urban planning, the concept of scientific rationality has been more consciously publicized in the field of urban planning, especially the application of system methodology in urban planning and the study of planning control since 1980s, especially the scientific nature of planning content has been more emphasized< The comprehensive concept of the whole city is the important ideological basis of modern urban planning and the direct embodiment of scientific rationality. Whether Howard's garden city or le Corbusier's tomorrow City, all factors in the city are considered comprehensively. Howard not only considered housing, employment, commerce and so on, but also focused on the implementation of garden city, involving urban finance, land system, commercial management and so on; Le Corbusier, on the basis of considering the employment, residence, transportation and other aspects of the city, especially emphasized the coordination of various elements. Urban planning under the guidance of modern architectural movement, in the process of practice, takes the organic coordination of various elements of the city as the core of the work. The Athens Charter elaborates this point of view in more detail. Modern urban planning has always regarded integrity and comprehensiveness as the most basic characteristics. This is also the content of urban planning in China
the concept of urban integrity and integration not only involves the relationship between various elements within the city, but also needs to consider the relationship between the city and its surrounding areas, which is the inevitable result of integrating various elements related to urban development. Therefore, the relationship between city and region has always been an important content of urban planning research. From this point of view, sustainable development advocated at home and abroad after the 1990s is a further deepening of this concept< The important difference between modern urban planning and traditional urban planning is that the traditional urban planning considers the organization and arrangement of the city from the perspective of the powerful to meet the interests of the ruling class and the rich class, while the modern urban planning is under the influence of utopian socialism, Under the influence of the concept of the city as a whole, we should not only take into account the requirements of only a small number of dignitaries, but also pay attention to the broad masses of urban citizens to meet the common requirements of all citizens. In order to solve the urban problems, we should pay special attention to the poor people in the city. It can even be said that modern urban planning starts from solving the problem of crowding, especially the living crowding of the working class, and improving the health condition of the city, especially the slums. On this basis, the values of urban planning with public interest as the core have graally formed, which is based on all citizens. In the later development, we still pay attention to the poor people. For example, the criticism of the consequences of the "urban renewal" movement in the United States, the emphasis on fairness and justice in the planning process, and public participation are all based on this
in addition, the research on people's activities in urban space and people's use of space also fully reflects the attention to people and people's needs in reality< 4. Social practice
urban planning is mainly concerned with public affairs and the control of market externalities. Therefore, urban planning must be a social undertaking. As a social undertaking, it must be better determined from the social structure, Because the scope of urban planning and what kind of role it can play are determined by this. It is obvious that modern urban planning in the west is graally formed and developed in the construction of social system. From a certain point of view, the knowledge framework of modern urban planning is mainly based on the idea of social reform, but the system construction of urban planning directly promotes the development of modern urban planning, The real function of urban planning is based on the modern urban planning system established after the Second World War. Similarly, urban planning, as a public affair, is closely related to the role of relevant governments and the development of relevant disciplines. The research on public policies in the West since the 1960s has also promoted the development of urban planning, *** And it is obvious that urban planning is widely accepted by the society with the reform of economic system (that is, the transformation from planned economy to market economy) and its deepening process.
