Homobimetallic Complexes of Platinum(II) Group Metals with Sulphur Containing Ligands R2C = CR2 (R = 5-Phenyl-1,3,4-Oxadiazole-2-Thiol; 4,5-Diphenyl-1,2,4-Triazole-3-Thiol or Mercaptobenzothiazole)

Abstract

Homobinuclear complexes of the type [Cl₂MR₂C=CR₂MCl₂] [M = Ni(II), Pd(II) or Pt(II) and R = 5-phenyl-1,3,4-oxadiazole-2-thiol; 4,5-diphenyl-1,2,4-triazole-3-thiol or mercaptobenzothiazole], have been prepared by the reaction of newly prepared sulphur containing ligands of the type R₂C=CR₂ with the appropriate metal

salts of Ni(II), Pd(II) or Pt(II). The complexes have been characterized

on the basis of their CHN elemental analysis, molar conductivity,

room temperature magnetic moment, I.R. and electronic

spectra. Octahedral enviroment around Ni(II) while square-planar

geometry around Pd(II) or Pt(II) have been deduced on the basis

of magnetic and spectral studies.
