A complex[Ni(L)(3,3′-bpt)2·(H2O)3]·H2O(1)(3,3′-bpt=3,5-bis(3-pyridyl)-1,2,4-triazole;H2L=2,2′-Dithio-salicylic acid)was synthesized under hydrothermal condition using 3,3′-Hbpt and 2,2′-Dithiosalicylic acid as the mixed ligands, and characterized by elemental analysis,IR spectroscopy and single crystal X-ray diffraction. Complex 1 crystallizes in Monoclinic space group P21 with a=7. 9020(16)Å,b=19. 152(4)Å,c=18. 196(4)Å,β=92. 69(3)°,V=2750. 7(10)Å3,Z=4,F(000)=1360,S=1. 067. The Ni(Ⅱ)display an octahedral coordination geometry. Each 3,3′-Hbpt links two adjacent Ni(Ⅱ)to generate an infinite 1D chain structure using its two pyridyl N atoms. The three dimensional network structure is constructed via the hydrogen bond interactions(CCDC:986971).%以1-氢-3,5-二(3-吡啶基)-1,2,4-三唑和2,2′-二硫二苯甲酸( H2 L)为混合配体与硝酸镍反应合水热成了一个镍配合物[Ni(L)(3,3′-bpt)2·(H2O)3]·H2O(3,3′-bpt=3,5-二(3-吡啶基)-1,2,4-三唑,L=脱质子2,2′-二硫二苯甲酸)(1)并利用元素分析、红外和X射线单晶衍射法对其结构进行了表征。结果表明标题配合物属于单斜晶系,P21空间群,晶胞参数为a=7．9020(16)Å,b=19．152(4)Å,c=18．196(4)Å,β=92．69(3)°,V=2750．7(10)Å3,Z=4,F(000)=1360,S=1．067。配合物中金属镍(Ⅱ)形成六配位畸变八面体构型,相邻的镍结构单元通过三唑配体的吡啶氮原子桥联形成一维无限链状结构,整个配合物通过丰富的氢键形成三维网络结构(CCDC：986971)。
