摘　　要：三氮唑配体具有丰富的配位模式,因而受到配位化学工作者的广泛关注,而第二配体的引入为新型配合物的合成提供了更多可能。本文以3,5-二甲基-4-氨基-1,2,4-三氮唑与对苯二酸混配,以Cd(Ⅱ)为中心金属离子,采用溶剂热法合成了一种新的三维配位聚合物{[Cd_(2)(DMTZ)(tp)_(2)(DMF)_(2)]·DMF}_(∞),并且采用单晶X-射线衍射法对其进行了结构表征。结果表明:该配合物属于单斜晶系,P 2_(1)/n空间群,a=11.8776(5)A,b=9.8448(3)A,c=30.7903(9)A,β=93.9840(10)°,R 1=0.0431,对其热稳定性及荧光性能进行了测定,结果表明该配合物有良好的光致发光性能,荧光发射峰位于450 nm处。For the variety of coordination modes,triazole compounds are widely concerned by coordination chemistry workers,and the introduction of the second ligand provides more possibilities for the synthesis of new complexes.A new three-dimensional coordination polymer,{[Cd_(2)(DMTZ)(tp)_(2)(DMF)_(2)]·DMF}∞was synthesized by solvothermal method with 3,5-dimethyl-4-amino-1,2,4-triazole and p-phthalic acid as ligand,and Cd(Ⅱ)as the central metal ion.Its structure was characterized by single crystal X-ray diffraction.The results show that the complex belongs to monoclinic system,P 2_(1)/n space group,a 11.8776(5)A,b 9.8448(3)A,c 30.7903(9)A,β93.9840(10)°,R_(1)0.0431.Thermal stability and fluorescence properties were determined.The results show that the complex has good photoluminescence properties with the emission peak at 450 nm.
