The dithiocarbonato metal complexes M(j 2 S,S-S 2 CO)(j 2 P,P-dppf) {M= Ni, Pd, Pt; dppf= bis(diphenylphosphino)ferrocene} are obtained from the reaction of the metal(II) complexes [M(j 2 S,S-S 2-COEt) 2 ] with the dppf ligand or from the chloride substitution of M(j 2 P,P-dppf)Cl 2 by the O-ethyldithiocabonato anion. These complexes are produced by CO bond cleavage by the O-ethyldithiocarbonato anion present in solution. These new complexes have been characterized by UV-Vis, NMR, IR spectroscopy and elemental analysis. The structures of the three complexes were further confirmed by single-crystal X-ray diffraction analysis.
