Synthesis and characterization complexes of bis (2-mercaptobenzimidazole)‎ mercury (II)‎ with transition metal (Ni (II)‎, Pd (II)‎, and Pt (II)‎)‎

الملخص EN

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.
