Six heteroatomic complexes of diphenylphosphine derivatives with heavy metals (Ni, Pd, Pt, Mo and W) were prepared and subjected to elemental spectral and thermal analyses. The different physicochemical methods used indicated the formulae [NiCl2(dppm)], [PtCl2(dppm)] and [Mo(CO)4(dppm)] (dppm = bis(diphenylphosphine)methane, the dppm in these complexes behaving as a bidentate ligand), [Pd(CN)2(dppm)2] (in which the dppm behaves as a monodentate ligand), [W(CO)4(dppe)2] and [Mo(CO)4(dppe)2] (dppe = 1,1-bis(diphenylphosphine)ethene, the dppe in these complexes behaving as a bidentate ligand). The thermal analyses (DTA and TG) confirmed these structures. The results of spectral and thermal analyses were compared.
