【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)(H_2(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 [CDB _ 2-mbab _ (bimb)] _ (1) and [Pb _ (2-sb) _ (2) were obtained by hydrothermal method. The structure of the coordination polymer [CDB _ 2-mbab _ (2-mba) _ 2-thiobenzoic acid) was characterized by elemental analysis, IR X-ray powder diffraction and single crystal diffraction were used to characterize the structure of the novel coordination polymer [CDB _ 2-mbab _ 2] _ (2) S _ (2) -benzoic acid) by means of elemental analysis, IR X-ray diffraction and single crystal diffraction. Complex 1 is a two-dimensional reticular structure formed by a one-dimensional [CD _ (2 ~ (2) m _ (ba))] _ n chain connected with bimb. The ligand 2-mercaptobenzoic acid in complex 2 was oxidized to 2-sulfobenzoate by in-situ reaction under solvothermal conditions. The structure is a layered structure connected by the carboxyl group of the ligand 2-sulfobenzoate and the lead ion bridged by the sulfonyl group. In addition, the two complexes exhibit good thermal stability and photoluminescence properties.
