摘　　要：The complex [Cu(m-NBA)(2,2'-bipy)(H2O)2]·m-NBA·H2O was obtained by self-assembly of m-nitroben-zoic acid,2,2'-bipyridine and copper(Ⅱ).The crystal structure of the complex has been determined by X-ray diffraction single crystal structure analysis.The crystal belongs to monoclinic system,space group P21/n.The cell parameters are:a=0.705 65(9) nm,b=2.901 2(4) nm,c=1.271 52(2) nm;β=92.895(2)°,and V=2.599 8(6) nm3,Dc= 1.551 g·cm-3,Z=4,μ(Mo Kα)=9.09 cm-1,F(000)=1 244,R1=0.040 7,wR2=0.085 5[I>2σ(I)].The crystal structure shows that the copper(Ⅱ) ion is coordinated with two nitrogen atoms from one 2,2'-bipyridine molecule,one oxygen atom from one m-nitrobenzoic acid molecule and and two oxygen atoms from two water molecules,forming a distorted coordination square-pyramid.The cyclic voltametric behavior of the complex was also studied.The complex [Cu（m-NBA）（2,2＇-bipy）（H20）2]·m-NBA·H2O was obtained by self-assembly of m-nitroben- zoic acid, 2,2＇-bipyridine and copper（Ⅱ）.
