A discrete bi nuclear copper(Ⅱ)complex containing Cu2 O2 unit has been syntheacterized by X-ray diffraction study and IR spectroscopy.The crystal is monoclinic,space group:P21/n,with unit cell parameters: a=8.2952(2),b=18.4633(3),c=10.5049(2)(A ).β=108.965(1)°,V=1521.56(5)(A)3,Z=2,C22H30N8O10Cl2Cu2,Mr=764.52,Dc=1.669 Mg/m3,F(000)=780,μ(MoKα)=8.60,T=293(2)K,final R=0.0623,wR=0.1536 for 2660 observed reflections with I ＞ 2.0σ(Ⅰ).The centrosymmetric complex Cu2(CH3O)2(C5H6N2)4(ClO4)2 comprises a pair of Cu(Ⅱ)atoms bridged by two methanoxo-and N-coordination 2-aminoppyridine.The Cu(Ⅱ)…Cu(Ⅱ)distance is 3.002(1)(A).
