摘 要:Mononuclear complex {[Cu(N-men)2(cda)2]·[Cu(N-men)2]-(ClO4)2} was synthesized by sodium carbamyldicyanomethanide Na(cda), N-methylethylenediamine and hydrate copper perchlorate. The crystal belongs to the triclinic system, space group P 1 with a = 7.229(2), b = 8.114(2), c = 15.936(4) A, α = 80.511(4), β = 78.993(4), r= 72.118(4)°, V = 867.6(3) A3, Z = 1, C20H44Cl2Cu2N14O10, Mr = 838.68, Dc = 1.605 g/cm3, F(000) = 434 and μ = 1.449 mm-1. The structure was refined to R = 0.0480 and wR = 0.1289 for 2503 observed reflections (I 2σ(I)). In the complex there exist two kinds of coordination models for Cu (II) ions. One is that the Cu (II) ion is coordinated by four nitrogen atoms which are from two N-men molecules, and a slightly distorted square planar coordinate environment is formed around the Cu (II) ion; the other is that the Cu (II) ion is coordinated by six nitrogen atoms, of which four are from two N-men molecules and the left from nitrile groups, resulting in a distorted octahedron around the
