Two cadmium coordination polymers, WSU-30 and WSU-31, were synthesized through solvothermal methods by using the low-symmetry TPE-based linker -HETTC. The -HETTC linker and both coordination polymers were fully characterized by using single-crystal X-ray diffraction, infrared spectroscopy, and photoluminescent emission spectroscopy. Structural analysis of WSU-30 and WSU-31 showed that each compound contains previously unknown tetranuclear cadmium(II) secondary building units. The topological analysis revealed that the 4,8-connected net of WSU-30 contains the underlying topology, alb-4,8-P21/c-1, while the mixed linker WSU-31 possesses a 3,10-connected net known as 3,10T31 topology. If the -ETTC linker is considered as two 3-connected nodes, WSU-30 possesses a very rare 3,3,8-connected 3,3,8T25 topology, and WSU-31 possesses a previously unknown 3,12-connected net, named 3,12T61.
两种镉配位聚合物，WSU-30 和 WSU-31，通过溶剂热法合成，使用低对称 TPE 基连接体 -HETTC。-HETTC 连接体和两个配位聚合物都通过单晶 X 射线衍射、红外光谱和光致发光发射光谱进行了充分的表征。WSU-30 和 WSU-31 的结构分析表明，每个化合物都包含以前未知的四核镉（II）二级建筑单元。拓扑分析表明，WSU-30 的 4,8 连接网包含基础拓扑结构 alb-4,8-P21/c-1，而混合连接体 WSU-31 具有称为 3,10T31 拓扑的 3,10 连接网。如果将 -ETTC 连接体视为两个 3 连接的节点，那么 WSU-30 具有非常罕见的 3,3,8 连接的 3,3,8T25 拓扑结构，而 WSU-31 具有以前未知的 3,12 连接网，命名为 3,12T61。
