The complex [Pt2H2(μ-H)(μ-dppm)2][PF6] (1) (dppm = Ph2PCH2PPh2) reacts with tertiary phosphine ligands to give H2 and the hydridoplatinum(I) complexes [Pt2HL(μ-dppm)2][PF6] (4, L = η1-dppm; 5, L = PMe2Ph; 6, L = PMePh2; 7, L = PPh3). Complex 4 is also obtained by the reduction of [Pt(dppm)2][PF6]2 with sodium borohydride. Study of the 1H and 31P NMR spectra of 4-7 is in accord with the presence of Pt-Pt bonds and, in the case of 4, shows that its structure in solution is similar to that previously determined in the solid state by an X-ray investigation. Methanethiol reacts reversibly with 4 to give [Pt2H2(μ-SMe)(μ-dppm)2][PF6]. Attempts to prepare diplatinum(0) complexes by deprotonation of 4 or 7 were unsuccessful.
