Synthesis and Crystal Structure of Chlorine Ion-bridged Binuclear Copper(II) Complex[Cu_2(Phen)_2Cl_2(μ-Cl)_2]

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=0.985 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,R1=0.122 6,wR2=0.173 9.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.
