• Reaction of PhHgX [X=ethylxanthate (xant) or <I>N</I>,<I>N</I>′-diethyldithiocarbamate (dtc)] with MX<SUB>2</SUB> [M=Ni(II), Pd(II) or Pt(II)] occurs, to afford a new class of golden green to yellowish brown organo heterobimetallic complexes, PhHgXMX<SUB>2</SUB> with MS<SUB>4</SUB> coordination geometry. The precursor PhHgX, have also been characterized. All the complexes are quite stable in solid and solution and are non-conducting species. In PhHgX, IR and NMR spectral studies suggest that dithio ligands are bound to phenylmercury in a linear fashion with additional Hg···S linkage in monodentate manner. Diamagnetism and electronic spectra indicate square planar geometry around M(II) in all the heterobimetallic complexes. IR and NMR spectral studies suggest the presence of monodentate and symmetrical bidentate dithio groups in heterobimetallic complexes.
