In this thesis, a series of complexes based on aromatic multicarboxylic acids have been successfully synthesized in solutions or under hydrothermal conditions. Their structure and properties are investigated.(1) Eight complex compounds have been synthesized and characterized by X-ray single crystal diffractive technology: The eight complexes are listed as following: [Cu242] complex 1 [Cd22(H2O)4]·4H2O complex 2 [Co(H2btc)(H2O)3] complex 3 [Co2(H2O)2]·H2O complex 4 [Ni22(H2O)4] complex 5 [Cu22(H2O)4] complex 6 [Co(H2biim)2(H2O)2](H2btc) complex 7 [Zn(H2biim)2(H2O)2](H2btc) complex 8 The structure of complex 1 is dinuclear complex resulted from weak interactions（0-D chain）; complex 2 is 1-D chain stucture result from interactions of water molecules; complex 3、4、5、6 are coordination polymers using hydrothermal synthses, where the first kind ligand is H4btc, the second kind ligand is phen and Co2+、Ni2+、Cu2+ as center ions, respectively. While the coordination enviroment of Co2+ is the same in complex 3, the coordination geometries around the Co atoms in complex 4 are obviously different because of the different reaction conditions. In complex 4, the 1-D chains are connected into 2-D layer through carboxy groups of ligand H4btc. The structures of complex 5、6 are 1-D chain stucture result from interactions of carboxy groups in ligand H4btc. Complex 7、8 are homeomorphy compounds. Either of them are linked to the 3-D chains through intermolecular hydrogen bonds. Each H4btc lose two protons and H2btc2- acts as negative electron balance.

合成了8个结构新颖的配合物，并用X-射线单晶结构分析方法确定了晶体结构，分别为： [Cu242] 配合物1 [Cd22(H2O)4]·4H2O 配合物2 [Co(H2btc)(H2O)3] 配合物3 [Co2(H2O)2]·H2O 配合物4 [Ni22(H2O)4] 配合物5 [Cu22(H2O)4] 配合物6 [Co(H2biim)2(H2O)2](H2btc)配合物7 [Zn(H2biim)2(H2O)2](H2btc)配合物8 配合物1是一个依靠弱作用连接的双核铜结构；配合物2借助水分子形成一维链状结构；配合物3、4、5、6是以H4btc为第一配体、phen为第二配体，通过水热法合成的配合物，其中，Co2+、Ni2+、Cu2+为中心离子；配合物3中的二价钴离子具有相同的配位环境，不同反应条件下得到的配合物4中的二价钴离子存在不同的配位环境，在配合物4中，一维链通过H4btc上的羧基形成一个二维层结构；配合物5、6是借助H4btc上的羧基形成的一维链状结构；配合物7、8属于异质同晶结构，它们的分子通过分子间氢键形成三维网状结构，H4btc上的羧基失去2个质子，作为一个二价负离子起到电荷平衡作用。

Last Monday, is expected to boost Shanghai aluminum in the Shouchu under Dikaigaozou to close small Line; last Tuesday Shanghai aluminum back slightly to close cross-Star; last Wednesday in a follow-up buying, Shanghai aluminum continue to move up slightly; last week Four official news reports, the State Reserve Bureau will be higher than the futures price and spot price of 12,300 yuan / ton Shouchu 300,000 tons of aluminum and aluminum hope that the State Reserve Bureau will reduce production capacity to carry out, under the boost in the news , Shanghai aluminum fell sharply after the Chonggao; copper last Friday for another new low aluminum prices also had a callback certain impact on the role of the Shanghai aluminum shocks down.

上周一，沪铝在收储预期提振下低开高走，收小阳线；上周二沪铝小幅回调，收十字星；上周三在买盘跟进下，沪铝继续小幅走高；上周四正式传出消息，国家储备局将以高于期货价格和现货价格的12300元/吨收储30万吨铝，并且国储局希望铝厂将压缩产能进行减产，在这一消息提振下，沪铝大幅冲高后回落；上周五沪铜再创新低对于铝价回调也产生了一定的影响作用，沪铝震荡回落。

King of the Sung Dynasty view country is in 《 learned wood · copper 斗》 have the tiny phrase to this type of phenomenon: any thing not with beautiful and bad, the something of well-known scholar calls, is happy with the so-called 伯 in… in valuable … on attending to, its price decuple.
