合成了3种金属配合物{[Cd(pztc)(H2O)2]·(H2bpy)·3(H2O)}n(1),{[Zn3(pztc)2(Hbpy)2(bpy)(H2O)4]·7H2O}n(2),[Cu6(pztc)4(Hbpy)4(bpy)2(H2O)8]·17H2O(3)(bpy=4,4′-联吡啶,H4pztc=吡嗪-2,3,5,6-四甲酸),并对其进行了红外光谱分析、元素分析、热重分析、荧光光谱分析和X-射线单晶衍射分析。其中1和3中存在丰富的氢键,2为3D网状结构,存在金鱼状(H2O)10水簇。3为由化学键连接成的1D链状结构,由氢键连接成3D超分子结构。当激发光波长为320 nm时,1和2的最大荧光发射峰分别在496 nm和494 nm。
Three kinds of metal complexes {[Cd (pztc) (H2O) 2] · (H2bpy) · 3 (H2O)} n (1) and {[Zn3 (pztc) 2 (Hbpy) 2 4] 7H2O} n (2) [Cu6 (pztc) 4 (Hbpy) 4 (bpy) 2 (H2O) 8] 17H2O (bpy = 2,3,5,6-tetracarboxylic acid), and its infrared spectroscopy, elemental analysis, thermogravimetric analysis, fluorescence spectroscopy and X-ray single crystal diffraction analysis. Among them, 1 and 3 are rich in hydrogen bonds, 2 is a 3D network structure, there is goldfish (H2O) 10 water cluster. 3 is connected by a chemical bond 1D chain structure, connected by hydrogen bonds into 3D supramolecular structure. When the excitation wavelength is 320 nm, the maximum fluorescence emission peaks of 1 and 2 are 496 nm and 494 nm, respectively.
