The bis(diphenylphisphino)ferrocene (dppf) derived palladium analogue of [PdCl2(dppf)] on reaction with the sodium salt of pyridyl/pyrimidyl selenolate yielded mononuclear cis configured complex [Pd(SeAr)2(dppf)] (Ar = C5H4N, C4H(4,6-Me)2N2), as did the platinum precursor [PtCl2(dppf)] with methyl substituted pyrimidyl salt giving [Pt{SeC4H(4,6-Me)2N2}2(dppf)]. In contrast, the reaction of platinum precursor with the sodium salt of pyridylselenolate gave two different complexes [Pt2(μ-SeC5H4N)2(dppf)2]2+ and [Pt(Cl)(SeC5H4N)(dppf)] depending in the reaction solvent. These complexes were characterized by elemental analysis and NMR (1H, 31P) spectroscopy. The molecular structure of [Pt{SeC4H(4,6-Me)2N2}2(dppf)] was established by single crystal X-ray diffraction analysis.
