| 摘 要： | 用四面体构型的配体四3-(羧基苯)氧甲基]甲烷(H4L)与镉离子通过溶剂热法合成了结构不同的配合物Cd6L3(DMA)3(H2O)]n (1)和{Cd2L(H2O)4]·4H2O}n (2)(L=四3-(羧基苯)氧甲基]甲烷)。化合物1属于三方晶系R3 空间群。每个配体通过4个羧基连接了4个三核镉簇, 每个三核镉簇连接了6个苯甲酸, 形成双节点(4, 6)-连接toc拓扑构型的三维骨架结构。配合物2属于单斜晶系C2/c空间群。每个配体连接了4个镉原子, 仍保持四面体构型。镉原子由羧基沿着b轴连接成一维链, 链与链之间通过配体连接, 且2个相邻配体的苯环之间存在π-π堆积。此外, 对化合物1和2在室温下做了固态紫外和荧光性质的研究。

| Abstract: | Two cadmium coordination polymers, Cd6L3(DMA)3(H2O)]n (1) and {Cd2L(H2O)4]·4H2O}n (2) (L=tetrakis3-(carboxyphenyl)oxamethyl]methane acid) with different structures have been synthesized based on a tetrahedral ligand L. Compound 1 crystallizes in the trigonal space group R3. The tetrahedral ligand connects four Cd3 clusters through its four carboxylates and the Cd3 clusters connect six benzoic rings to form a 4,6-connected 3-dimentional framework of the toc topology. Compound 2 crystallizes in the monoclinic C2/c space group. Each ligand connects four cadmium atoms and the cadmium atoms are connected through carboxylates to form a chain along the b axis. The solid-state UV-Vis spectra and photoluminescent properties of 1 and 2 were investigated at room tempreture. |
