摘　　要：通过水热法成功合成了一例化合物{[(3,3′-Hbpt)Cd(bta)0.5(H2O)]·(H2O)}n(1)(3,3′-Hbpt=3,5-二(3-吡啶基)-1-H-1,2,4-三唑(3,3′-Hbpt);H4bta=均苯四酸),并通过X射线单晶衍射、元素分析、X射线粉末衍射和荧光光谱等方法对该化合物进行了结构表征和性质研究.X射线单晶衍射分析表明,化合物1属于单斜晶系,P21/n空间群,晶胞参数为a=1.14643(14)nm、b=0.95752(11)nm、c=1.69171(19)nm、α=90°、β=102.029(2)°、γ=90°、V=1.8163 nm^3、Dc=1.817 g/cm^3、Z=4、F(000)=988和GOOF=0.856.此外,通过荧光光谱对化合物1的荧光性质进行了研究.Based on the organic ligand 1H-3-(3-pyridyl)-5-(3′-pyridyl)-1,2,4-triazole(3,3′-Hbpt)and 1,2,4,5-Benzenetetracarboxylic acid(H4bta),a compound{[(3,3′-Hbpt)Cd(bta)0.5(H2O)]·(H2O)}n(1)was hydrothermally self-assembled,which was further characterized by X-ray single-crystal diffraction,elemental analysis,and power X-ray diffraction.Single crystal X-ray structure analysis revealed that 1 belonged to a monoclinic system with space group P21/n,and the cell parameters are a=1.14643(14)nm,b=0.95752(11)nm,c=1.69171(19)nm,α=90°,β=102.029(2)°,γ=90°,V=1816.3 nm^3,Dc=1.817 g/cm^3,Z=4,F(000)=988,and GOOF=0.856.In addition,the fluorescence properties of the 1 were also studied by fluorescence spectroscopy.
