摘　　要：合成了二氯二(对溴苯胺)合锌(Ⅱ)配合物ZnCl2(p BrC6H4NH2)2,并测定了该配合物分子的晶体结构.该晶体属单斜晶系,空间群为C2 c,晶胞参数:a=3.1802(6)nm,b=0.46893(9)nm,c=1.1803(2)nm,β=110.83(3)°,V=1.6451(6)nm3,Z=4,Dc=1.939g·cm-3.对于1348(I≥2σ(I))个可观察点,最终偏差因子R=0.0565,wR=0.1538.两个对溴苯胺的2个胺基N原子和2个Cl-与Zn(Ⅱ)离子配位,形成畸变四面体Cl2N2Zn配位构型.The title complex ZnCl\-2(pBrC\-6H\-4NH\-2)\-2 was synthesized and characterized by Xray diffraction analysis.The crystal crystallizes in monoclinic system,space group C 2/c with a=3.180 2(6) nm,b=0.468 93(9) nm,c=1.180 3(2) nm,β=110.83(3)°,V=1.645 1(6) nm\+3,Z=4,D\-c=1.939 \{g·cm\+\{-3\}\},μ=6.662 mm\+\{-1\} (Mo K\-α),F(000)=928. The structure was refined to R=\{0.056 5\} and \{wR=\}\{0.153 8\} for observed 1 348 reflections with I≥2σ(I). The Zn(Ⅱ) ion has a distorted tetrahedron coordination composed of two nitrogen atoms from pbromoaniline molecules and from two choric anions.
