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.%Two coordination polymers,[Cd2(L)(DMF)1.5(H2O)2]n (1) and {[Cd(L)0s(4,4'-bpy)(H2O)] ·2H2O}n (2),have been designed and synthesized by solvothermal or hydrothermal reactions of 5,5'-(aexane-1,6-diyl)-bis (oxy) diisophthalic acid ligand (H4L) with Cd(lⅡ) 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 Schlafli symbol of (66)(64· 82).Additionally,complexes 1 and 2 present better thermal stabilities,and show different photoluminescence behaviors in the solid state.CCDC:1497548,1;1497549,2.
