摘要：

The arsine complexes [Cu(AsPh(3))(2)(LH)X] (LH = N,N-dimethyl-N'-phenylthiourea (dmptH), N,N-dibutyl-N'-phenylthiourea (dbptH) or 1,3-thiazolidine-2-thione (tzdtH); X = Cl, Br, I) have been prepared and characterized on the basis of analytical, IR, electronic (UV-vis), H-1 NMR, conductivity and magnetic measurements. In all cases there is a distorted tetrahedral environment around copper(I) and the ligands (LH) bind through thione sulphur atom to copper(I). We also report the crystal structure of complex [Cu(PPh(3))(2)(dmptH)Cl] which shows that metal ion has a distorted tetrahedral geometry with bond lengths Cu-S=2.459(2), Cu-Cl=2.308(1), Cu-P(1)=2.305(1) and Cu-P(2) = 2.313(1) Angstrom. The NH is intramolecularly hydrogen bonded to Cl with a bond distance NH ... Cl = 2.31 Angstrom.
