Synthesis and Crystal Structure of a New Mononuclear Cu(II) Complex with 4,4'-Dimethyl-2,2'-bipyridine

摘要

A new mononuclear copper (II) complex,[Cu(dbpy)2Cl]·OH·0.5CH3OH·2H2O (dbpy = 4,4'-dimethyl-2,2'-bipyridine) (C24.50H31ClCuN4O3.50,Mr = 536.52) has been synthesized and its crystal structure was determined by X-ray diffraction method.It crystallizes in monoclinic,space group P2/c with a = 13.383(6),b = 7.653(3),c = 14.164(6)(A),β= 105.395(8)o,V = 1398.7(10)(A)3,Z = 2,Dc = 1.274 g/cm3,(=0.908 mm-1,F(000) = 560 and R = 0.0773 for 1467 observed reflections with I>2б(I).Each copper(II) ion is coordinated by two dbpy and one Cl-ion and the coordination geometry can be described as a distorted trigonal bipyramidal arrangement.
