摘　　要：在水溶液中合成了氯离子桥联的双核铜(Ⅱ)配合物[Cu2(Phen)2Cl2(μ-Cl)2],其结构经IR,元素分析和X-衍射表征,结果表明,配合物属单斜晶系,空间群Cc,晶胞参数为:a=0.985 7(3)nm,b=1.783 5(6)nm,c=1.337 8(5)nm,β=106.617(7)°,V=2.254(1)nm3,Z=4,Dc=1.855 g.cm-3,μ=2.385 mm-1,F(000)=1 256,偏差因子R1=0.122 6,wR2=0.173 9。配合物为双核络分子,每个金属铜离子与邻菲咯啉配体的2个N原子和3个Cl-离子配位形成畸变四方锥结构,配位多面体通过两氯离子形成共棱的双四方锥,通过氢键和芳环堆积作用,络分子形成三维网络结构。A novel complex, chlorine ion-bridged binuclear copper（Ⅱ complex[Cu2（Phen）2Cl2（μ-Cl）2], was synthesized in water-ethanol solution and the crystal structure was determined by IR, elemental analysis and X-ray diffraction. The results showed that crystal belongs to monoclinic system, space group Cc with a=0.9857（3）nm,b=1.7835（6）nm,c=1.3378（5）nm,β=106.617（7）°,V=2.254（1）nm^3,Z=4,Dc=1.855g.cm^3,μ=2.385mm^-1,F（000）=1256,偏差因子R1=0.1226,wR2=0.1739. The complex possesses a binuclear molecule structure, in which the two Cu（ Ⅱ ） ion are each coordinated by two N atoms and three Cl^- anions from phenanthroline to form distorted square pyramids. Two adjacent polyhedrons are condensed via two bridging Cl^- anions to result in an edge-shared bi-square-pyramid. Through the intermolecular π-π stacking interactions and hydrogen bonds, the complex molecules assembles into a 3D network.
