Three two-dimensional coordination polymers [Cd(2,3-Pyma)Cl2] n (I), [Cd(2,3-Pyma)(1,4-Chdc)] · 4H2O}n (II) and [Zn2(2,3-Pyma)(1,2,4,5-Bttc)(H2O)4] · 6H2O} n (III) (2,3-Pyma = (2,3-pyridylmethyl) amine, H2-1,4-Chdc = 1,4-cyclohexanedicarboxylic acid, and H4-1,2,4,5-Bttc = 1,2,4,5-benzenetetracarboxylic acid) have been synthesized and structurally characterized by single crystal X-ray crystallography
三种二维配位聚合物[Cd(2,3-Pyma)Cl 2 ] n(I),[Cd(2,3-Pyma)(1,4-Chdc)]·4H 2 O} n(II)和[Zn 2(2,3-Pyma)(1,2,4,5-Bttc)(H 2 O)4 ]·6H 2 O} n(III)(2,3-Pyma =(2,3 -吡啶基甲基)胺,H 2 -1,4-Chdc = 1,4-环己烷二甲酸和H 4 -1,2,4,5-Bttc = 1,2,4,5-苯四甲酸)并合成结构上通过单晶X射线晶体学表征(CIF文件CCDC号989461(I),1055685( II)和1055686(III))。三个复合物都是由柔性2,3-Pyma配体或羧酸酯配体桥接的二维层网络。注意到,柔性的1,4-Chdc配体将Cd 2+离子结合成络合物II中的螺旋链结构。研究了光致发光和热性能。
