| 摘要: 通过溶剂热和水热合成的方法制备了2个Cd（Ⅱ）配位聚合物[Cd2（L）（DMF）1.5（H2O）2]n（1）和{[Cd（L）0.5（4，4'-bpy）（H2O）]·2H2O}n（2）（H4L=5，5'-（己烷-1，6）-双-（氧基）-二-间苯二甲酸）。结构分析表明配合物1是一个（4，4）-连接的sql拓扑网络，拓扑符号为{44·62}2。配合物2是一个（4，4，4）-连接的三重穿插的bbf网络，拓扑符号为（66）（64·82）。配合物1和2都呈现出较好的热稳定性和荧光性质。 | |

| Abstract: Two coordination polymers,[Cd2(L)(DMF)1.5(H2O)2]n (1) and {[Cd(L)0.5(4,4'-bpy)(H2O)]·2H2O}n (2), have been designed and synthesized by solvothermal or hydrothermal reactions of 5,5'-(hexane-1,6-diyl)-bis(oxy)diisophthalic acid ligand (H4L) with Cd(Ⅱ) metal ions in the presence/absence of N-donor ligands. The structures of 1~2 have been determined by single-crystal X-ray diffraction analyses and further characterized via infrared spectra (IR), powder X-ray diffraction (PXRD), elemental analyses and thermogravimetric (TG) analyses. Complex 1 features a (4,4)-connected sql topology net with point symbol of {44·62}2. Complex 2 presents a trinodal (4,4,4)-connected 3D 3-fold interpenetrating bbf network with a Schläfli symbol of (66)(64·82). Additionally, complexes 1 and 2 present better thermal stabilities, and show different photoluminescence behaviors in the solid state. | |
