摘　　要：以3-(吡嗪-2,5-基)-1,2,4-三氮唑(Hpztz)和硫酸镉为原料,通过水热反应合成了一例零维的双核Cd(Ⅱ)超分子配合物(即配合物1)。并对其晶体结构、固态荧光性质进行了测定。X-射线衍射分析表明:配合物1主体结构是一个双核带正电荷的[Cd_(2)(H_(2)O)_(6)(pztz)_(2)]^(2+)超分子,其电荷由外界游离的SO_(4)^(2-)平衡,相邻的双核[Cd_(2)(H_(2)O)_(6)(pztz)_(2)]^(2+)超分子通过氢键以及与SO_(4)^(2-)的静电作用相互堆积拓展到三维。室温下固体荧光分析表明,配合物1在260 nm波长激发光谱条件下于391 nm处表现出了最强的发射峰。A 0 D binuclear supramolecular compound(compound 1)was constructed by hydrothermal reaction with 3-(pyrazin-2,5-yl)-1,2,4-triazole(Hpztz)and cadmium sulfate as the raw materials.The crystal structure and solid state fluorescence properties of compound 1 was determined.X-ray diffraction analysis show that the main structure of compound 1 is a binuclear[Cd_(2)(H_(2)O)_(6)(pztz)_(2)]^(2+)complex cation,whose charge is balanced by the dissociative SO_(4)^(2-).The adjacent binuclear[Cd_(2)(H_(2)O)_(6)(pztz)_(2)]^(2+)supramolecules expand into a 3 D structure through H-bond and electrostatic interactions between thebinuclear[Cd_(2)(H_(2)O)_(6)(pztz)_(2)]^(2+)supramolecules and SO_(4)^(2-).Solid fluorescence analysis at room temperature showed that compound 1 exhibited the strongest emission peak at 391 nm under the excitation spectrum of 260 nm.
