摘要： The crystal and molecular structure of copper(Ⅱ) dimeric complex of S-methyl-B-N-(pyridine N-oxide-2-ylmethylidene) dithiocarbazate with acetonitrile, [CuL(CH3CN)]2(ClO4)2, was determined by X-ray diffraction. The complex crystalizes in monoclinic system with space group P21/n, a= 7.685(2), 6=20.160(6), c= 10.847(5) Å,B=107.89(3), Z=2,Dc=1.788g/cm3, F(000)=835.8, u= 18.17 cm-1(Moka,R= 0.057.Each Cu(Ⅱ) ion in the complex is surrounded by a distorted square pyramidal. The basal plane is comprised of S, Nand Oatoms of one ligand together with a Natom of the solvent--acetonitrile, while the axial position is occupied by the Satom of the other ligand. The bond length of Cu-S(bridging) is 3.038A. and Cu-Cu distance is 3.700A.
