Synthesis and characterization of bis (5-phenyl-1,3,4-oxadiazole-2-ylthio) mercury complexes with Pd(II) and Pt(II) metal ions

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-2ylthio)mercury (HgL 2) with two mole of PdCl 2 and PtCl 2 to give the colored complexes with general formula [M 2 Cl 4 (HgL 2)] [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 (HgL 2). Characterization have been done by using FT-IR Spectroscopy, H 1-NMR spectroscopy, UV-visible spectra, melting point and CHNS analysis.
