Manganese(Ⅱ) and Cadmium(Ⅱ) Mixed-Ligand Complexes Constructed from Benzimidazole-5,6-dicarboxylic Acid: Syntheses, Crystal Structures and Properties

在水热条件下,合成了2个配位聚合物{[Mn(Hbidc)(2,2′-bpy)(H_2O)_2]·1.5H_2O}n(1)和{[Cd(Hbidc)(phen)][Cd(phen)_2Cl_2]}n(2)(H_3bidc=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。

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.
