中文摘要：

为了研究半刚性配体构筑金属配位聚合物的自组装规律,选用两种不同长度的含N半刚性配体与Co^Ⅱ离子,在水热反应的条件下,构筑了两个新的配位聚合物[Co（L1）（m-BDC）]n（1）和{[Co（L2）（m-BDC）]·H2O}n（2）（L1=1,3-二（咪唑亚甲基）苯;L2=4,4’-二（咪唑亚甲基）联苯）,并对这两个配合物进行了元素分析、红外、粉末X-射线衍射、热重分析和单晶X-射线衍射表征。结构分析表明,这两个配合物均具有二维的（4,4）-网格结构,但由于配体长度的不同,网格结构展现出了不同的形状与尺寸。此外,热重分析表明,这两种配合物均具有较高的热稳定性。

英文摘要：

To investigate self-assembly of coordination polymers based on semi-rigid ligands, two coordination polymers constructed by metal cobalt and N-donor semi-rigid ligands with different lengths, namely, [ Co （ L1 ） （ m-SDC ） ]n （ 1 ） and / [ Co （L2） （ m-BDC ） ]·H2O/n （2）, { L1 = 1,3-bis （ imidazol-l-ylmethyl） benzene, L2 = 4,4＇ -bis （ imidazol-l-yl-methyl ） biphenyl / , have been hydrothermally synthe- sized. Structures of the coordination polymers 1 and 2 were characterized by elemental analysis, IR, PXRD, TGA and X-ray single crystal diffraction. Two-dimensional （4,4）-networks were observed in both polymers and exhibited different shapes and dimensions due to the different ligand lengths. Finally, the TGA investigation indicated high thermal stabilities of these two polymers.
