摘　　要：采用溶液法合成了一维链状4,4'-联吡啶铜配合物{[Cu_2(OOCCH_3)4(4,4-bpy)]·(CH_3CN)}n(4,4-bpy=4,4'-联吡啶),经单晶X射线衍射测定其晶体结构。此晶体属单斜晶系,空间群C2/c。晶胞参数:a=2.311 67(5)nm,b=1.400 23(2)nm,c=1.531 03(4)nm,β=108.205(2)°,V=4.707 69(17)nm^3,F(000)=2 288,Z=8,D_c=1.582 g/cm^3,μ=1.850 mm^(-1),R1=0.033 6,ωR^2=0.093 5。晶体结构分析表明,配合物中心Cu^(2+)形成了变形的几何四方锥CuNO_4构型,Cu^(2+)通过4个乙酸根桥连形成双核单元,双核单元再通过4,4'-联吡啶N原子桥联成一维链状,经分子间范德华力作用构造出了三维超分子网。The title complex was synthesized in the reaction by 4,4＇-bipyridine and cupric acetate in acetonitrile DMF solution.The crystal structure was determined by single crystal X-ray diffraction.The crystal structure of the title complex belongs to the monoclinic system with space group C2/c and cell parameters：a=2.311 67（5）nm,b=1.400 23（2） nm,c=1.531 03（4） nm,β=108.205（2） °,V=4.707 69（17） nm^3,F（000） =2 288,Z=8,Dc=1.582 g/cm^3,μ=1.850 mm^（-1）,R_1= 0.033 6,ωR_2= 0.093 5.The Cu（II） was coordinated by four oxygen atoms from OOCCH_3 groups and one nitrogen atom from 4,4＇-bipyridine,and formed a distorted square pyramidal geometrical configuration.The complex formed a dimer through OOCCH_3 bridges which constructed a one dimensional chain.The 1D chain further formed 3D network through the van der Waals force.
