摘要: 通过水热合成的方法制得具有三维超分子结构的2种配位聚合物{[Zn(L)(bpa)0.5(H2O)2]·2.25H2O}n1)和{[Cd(L)(H2O)]·2H2O}n2),其中,H3LCl为氯化5-(4-羟基吡啶基甲基)间苯二甲酸,bpa为1,2-二(4-吡啶基)乙烷。这2种化合物的结构通过单晶X射线衍射、红外光谱(IR)、元素分析、热重分析(TG)等方法进行了表征。结构解析表明:化合物1是一种梯型链式结构,并通过链间氢键作用延伸成了3D超分子网络;化合物2为含有大量一维隧道空腔的2D配位网络。此外,研究了这2种化合物的荧光性质。

Abstract: Two coordination polymers with 3D supramolecular network, {[Zn(L)(bpa)0.5(H2O)2]·2.25H2O}n (1) and {[Cd(L)(H2O)]·2H2O}n (2) (H3LCl=5-(4-hydroxypyridinium-1-ylmethyl) isophthalic acid chloride, bpa=1,2-bis(4-pyridyl)ethane) were hydrothermally synthesized and structurally characterized by X-ray diffraction analyses and further characterized by infrared spectra (IR), elemental analyses, and thermogravimetric (TG) analyses. Compound 1 exhibits a ladder-like chain structure, and such chains are further united together to generate a 3D supramolecular structure through the hydrogen bonding interactions. Compound 2 possesses a 2D coordination network with a 1D channel that run parallel to the coordination layers. Meanwhile, their luminescent properties have also been investigated in detail.
Keywords: 5-(4-hydroxypyridinium-1-ylmethyl) isophthalic acid chloride  1,2-bis (4-pyridyl) ethane  zinc  cadmium
