摘　　要：采用乙二胺水杨醛Schiff碱配体与水合硝酸铜配位生成了一雁形的双核Cu(Ⅱ)配合物,产物通过了元素分析、红外光谱及单晶X射线衍射分析等手段的证实。结果表明,该配合物晶体属于单斜晶系,P21/c空间群,晶胞参数为:a=0.8559(14),b=2.3276(4),c=1.1057(18)nm,β=91.360(4)°,V=2.2021(6)nm3,Z=2,Dc=1.706g/cm3,Mr=1130.82,R1=0.0543,wR2=0.1522;结构分析表明,配合物中存在两种截然不同的Cu(Ⅱ)配位模式,Cu(1)离子采取四方平面构型,Cu(2)离子却为扭曲八面体几何构型。A wild goose-like copper（II） complex has been prepared by coordination reaction of ethylenediamine salicylaldehyde Schiff base ligand and cupric nitrate trihydrate. The structure also has been confirmed by the methods of elemental analysis, IR spectra and single crystal X ray diffraction analysis. The structural analysis reveals that the complex belongs to monoclinic system, the space group is P21/c,with the crystal cell parameters a=0. 8559（14.） ,b=2. 3276（4） ,c= 1. 1057（18） nm,β= 91. 360（4）°, V= 2. 2021 （6） nm3, Z = 2, Dc = 1. 706g/cm3, Mr = 1130. 82, R1 = 0. 0543, wR2 = 0. 1522. It is worth noting that there are two crystallo- graphic distinct copper（II） ions in the structure, one copper（II） ion adopted square planar geometry, in contrast, the other is in an octahedral coordination environment.
