2,2’-二(1,1’-4-甲基-吡啶)联咪唑(L)、芳香二羧酸与乙酸镉在水热条件下反应得到了配位聚合物[Cd2(L)(p-bdc)2(H2O)2]n(1)和[Cd(L)0.5(m-bdc)]n(2),并用单晶衍射仪定义了其晶体结构.结构分析表明,配合物1结晶属于正交晶系,Ibca空间群,配合物2结晶属于单斜晶系,C2/c空间群,进一步分析表明,所合成的2个化合物都是有扭曲α-Po拓扑的三维网络结构.在室温条件下,配体L和2个配合物均表现出较好的荧光性质.
Two novel polymers, [Cd2 (L) (p-bdc)2 (H2O)2 n (1) and [Cd(L)0.5 (m-bdc) ]n (2) based on 1,1'-bis(pyridin-4-ylmethyl)-2,2'-biimidazole (L) ligand, Cd(OAC)2 and benzenedicarboxylate iso- mers, have been synthesized under hydrothermal conditions. Their stuetures have been characterized by single crystal X-ray diffraction analyses. The results show that both compouds 1 and 2 exhibit 3D frameworks with a-Po topologies, in which compound 1 crystallizes in the orthorhombic space group Ibca and compound 2 crystallizes in the monoclinic space group C2/c. In addition, ligand L, com- pounds 1 and 2. show good fluorescences in the solid state at room temperature.
