Synthesis and characterization of new metal complexes of thione and phosphines Ligands

Abstract

The complexes containing mixed of ligands [5-(3-chlorophenyl) -1,3,4-oxadiazole-2-thione(CPoxSH)] and diphosphines Ph2P(CH2)nPPh2 (diphos)(n=1-4), are prepared by the reaction of [Hg(CPoxS)2] or [M(H2O)2(CPoxS)2] (M = Co, Ni ) with one mole proportion of the diphosphine Ph2P(CH2)nPPh2 gave tetrahedral complexes of the type [Hg(CPoxS)2(diphos)]. While gave an octahedral complexes with cobalt(II) and nickel(II) ions of the type [M(H2O)(CPoxS)2(diphos)] when (M = Co and Ni ) receptivity.
 The prepared complexes were characterized by molar conductivity, elemental analysis, IR, 1H, 13C-{1H} and 31P-{1H} n.m.r.
