| 摘要: 在水热条件下，合成了2个配位聚合物{[Mn（Hbidc）（2，2'-bpy）（H2O）2]·1.5H2O}n（1）和{[Cd（Hbidc）（phen）][Cd（phen）2Cl2]}n（2）（H3bidc=苯并咪唑-5，6-二羧酸，2，2'-bpy=2，2'-联吡啶，phen=菲咯啉），并通过X射线单晶衍射、红外、元素分析、X射线粉末衍射和热重对配合物结构进行了表征。配合物1是一维无限zig-zag链结构，可以通过O-H…O和N-H…O氢键的相互作用形成三维超分子结构。配合物2也是一维无限链结构。此外，测试了配合物1和2的固体紫外吸收光谱和研究了配合物2的固体荧光性能。 | |

| Abstract: Two coordination polymer, {[Mn(Hbidc)(2,2'-bpy)(H2O)2]·1.5H2O}n (1) and {[Cd(Hbidc)(phen)] [Cd(phen)2 Cl2]}n (2) (H3bidc=benzimidazole-5,6-dicarboxylic acid, 2,2'-bpy=2,2'-bipyridine and phen=1,10-phenanthroline) have been synthesized under hydrothermal method. They were characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis, powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). Complex 1 exhibits one-dimensional infinite zig-zag chain, which is extended into a three dimensional supramole-cular network via O-H…O and N-H…O hydrogen bonding interactions. Complex 2 also possesses one dimen-sional chain structure. In addition, the UV-Vis absorption spectra of 1 and 2 were measured at room temperature and the solid fluorescent property of 2 was studied at room temperature. | |
