Abstract

The cyclometalated complexes [Pt(ppy)R(SMe2)] or [Pt(bhq)R(SMe2)], where ppyH = 2-phenylpyridine, bhqH = benzo[h]quinoline and R = methyl or p-tolyl, react with bis(diphenylphosphino)ethane, dppe, in a 1 : 1 ratio to give the corresponding complexes [Pt(κ1-C-ppy)R(dppe)] or [Pt(κ1-C-bhq)R(dppe)], in which the ppy or bhq ligands are monodentate and dppe is chelating. The similar reaction in a 2 : 1 ratio gives the binuclear complexes [{Pt(ppy)R}2(μ-dppe)] or [{Pt(bhq)R}2(μ-dppe)], in which the dppe ligands are in the unusual bridging bidentate bonding mode.
