| 摘 要： | 由水热法得到2个新颖配位聚合物Cd(2-mba)(bimb)]n(1)和Pb(2-sb)]n(2)(H2(2-mba)=2-巯基苯甲酸, bimb=4,4-双(1-咪唑基)联苯,sb2-=2-亚磺基苯甲酸酯) 通过元素分析、红外光谱、X射线粉末衍射和单晶衍射对其进行了表征。配合物1为二维网状结构,由一维的Cd(2-mba)]n链与bimb连接形成。在配合物2中配体2-巯基苯甲酸在溶剂热的条件下通过原位反应被氧化成2-亚磺基苯甲酸酯,其结构为一种由配体2-亚磺基苯甲酸酯中的羧基与亚磺基桥联金属铅离子形成的二维(4,4)连接的层状结构。此外,2个配合物展示了良好的热稳定性和光致发光性能。

| Abstract: | Two novel coordination polymers, Cd(2-mba)(bimb)]n(1) and Pb(2-sb)]n(2) H2(2-mba)=2-mercaptobenzoic acid, bimb=4,4-bis(1-imidazolyl)bibenzene, sb2-=2-sulfinobenzoate] have been solvothermal synthesized and characterized by elemental analysis, IR, powder X-ray diffraction and single crystal X-ray diffraction. Complex 1 features a two-dimensional (2D) net structure in which 1D Cd(2-mba)]n chains are interconnected by bimb ligands. In complex 1, the ligand 2-mercaptobenzoic acid was oxidized into 2-sulfinobenzoate under solvothermal conditions via in situ ligand reactions. Complex 2 exhibits a 2D(4, 4)-connected framework bridged with carboxylate and sulfinate groups of 2-sulfinobenzoate ligands. The thermal stabilities and solid state photoluminescent properties of two compounds were also investigated. |
