Three new Cd^II coordination polymers (CPs) have been synthesized by hydrothermal reactions of Cd(OAc)₂, 1,2,5‐thiadiazole‐3,4‐dicarboxylic acid (H₂tdzdc), and distinct N/O‐donor ligands. They exhibit two‐dimensional (2D) and three‐dimensional (3D) structures with different topology networks including rob, zzx, and cem. The introduction of 4,4‐bipyridine (4,4‐bipy), [4,4‐bipyridine]1,1‐dioxide (Obpy), and 1,4‐bis((1H‐1,2,4‐triazol‐1‐yl)methyl)benzene (tmb) is a favor for the construction of interpenetrated networks. Moreover, the luminescent properties of 1, 2, and 3 have been investigated in detail by experiment and theoretical methods. Density functional theory (DFT) calculations indicate that the electron would be transferred from metal to ligand in the excitation of compound 3.

通过选择三种中性和两性离子N / O供体配体来调谐新型Cd（II）拓扑网络：合成，结构和荧光

三个新的镉^II配位聚合物（CPS）已经通过（OAC）镉水热反应合成₂，1,2,5-噻二唑-3,4-二羧酸（H ₂ tdzdc），且不同的N / O供体配体。它们表现出具有不同拓扑网络（包括rob，zzx和cem）的二维（2D）和三维（3D）结构。引入4,4-联吡啶（4,4-联吡啶），[4,4-联吡啶] 1,1-二氧化物（Obpy）和1,4-双（（1 H -1,1,2,4-三唑-1-基）甲基）苯（tmb）对于构建互穿网络非常有用。此外，发光性能1，2，和3已经通过实验和理论方法进行了详细研究。密度泛函理论（DFT）计算表明，在化合物3的激发中，电子将从金属转移到配体。
