cis-PtCl2(PHCy2)2 (1) reacts at 0°C in toluene with sodium metal to give the dinuclear PtI complexes cis-[(PHCy2)-(H)Pt(μ-PCy2)]2 (2) and [(PHCy2)(Cl)Pt(μ-PCy2)Pt (PHCy2)2]-(Pt-Pt) (3). On standing in solution, complex 3 isomerizes to trans-[(PHCy2)(Cl)Pt(μ-PCy2) 2Pt(PHCy2)(H)] (4). When treated with sodium at room temperature, complex 3 transforms into [Pt(μ-PCy2)(PHCy2)]2(Pt-Pt) (5). The sodium reduction of 1 carried out at room temperature leads to the direct formation of the phosphido bridged dinuclear complex [Pt(μ-PCy2)(PHCy2)]2(Pt-Pt) (5) along with the mononuclear platinum(II) complex [trans-Pt(PCy2H)2(PCy2)Cl] (6). Complex 6, which has also been obtained by reaction of 1 with LiPCy2, unambiguously shows by single-crystal X-ray diffraction the presence of a pyramidal terminal phosphido ligand.
