Abstract

A complexes of Pd(II) and Pt(II) have been synthesized from a reaction of one mole of (5-phenyl-1,3,4-oxadiazole-2-ylthio)mercury (HgL₂) with two mole of PdCl₂ and PtCl₂ to give the colored complexes with general formula [M₂Cl₄(HgL₂)] [where M=Pd(II) or Pt(II)]. The results of identification indicated that all complexes have square planer shapes, which the metal coordinates to the ligand through Nitrogen, and Sulfur atoms of ligand (HgL₂). Characterization have been done by using FT- IR Spectroscopy, H¹-NMR spectroscopy, UV-visible spectra, melting point and CHNS analysis.
