Abstract

Treatment of 2-Mercaptobenzimidazol (HL) with the mercuric acetate (Hg(OAc)₂) give the complex[Hg(L)₂] (1). Then the multinuclear complexes of the type [M₂Hg₂(L)₄Cl₄] were prepared through the reaction of complex (1) with each of NiCl₂.6H₂O, PdCl₂ and PtCl₂ in (2:2) molar ratio. All complexes were described using infrared spectra, Proton Nuclear Magnetic Resonance , Carbon 13- Nuclear Magnetic Resonance , ultraviolet-visible, atomic absorption spectroscopy, CHNS analysis, molar conductivity, determination of Chloride Percentage and magnetic susceptibility measurements.The heterocyclic ligand is expected to be coordinated to two or single metal atom through the nitrogen atom and sulphur atom or by only sulphur atom.
