PREPARATION AND CRYSTAL STRUCTURE OF A HETEROBINUC- LEAR COPPER (Ⅱ)-ZINC(Ⅱ) COMPLEX WITH μ-OXAMIDO LIGAND

<正> The complex Cu(oxap)Zn(phen)2](ClO4)2·H2O·CH3CH2OCH2-CH3(Mr = 980. 61) (oxap = N,N'-bis(2-aminopropyl) oxamido C2O2 (NCH2CH(CH3) NH2)2, phen = 1, 10-phenanthroline) crystallizes in the monoclinic space group P21/n with a=13. 076(4),b=23. 039(7) ,c= 14. 375(3) A,β=98. 11(2)°,V = 4287. 2A3, Z = 4,DX = 1. 541g/cm3,μ=12. 80cm-1 and F(000) = 2020. The final refinement converged with R=0. 067 for 3173 observed independent reflections. The copper(Ⅱ) ion is in an almost planar tetragonal environment while the zinc(Ⅱ) ion is in a distorted octahedron. The Cu....Zn distance is 5. 265A.
