Heterobimetallic complexes such as [η-areneMCl(SPPh₂)₂Pt(S₂CNEt₂)] (I, M = Ru, Os) and [η-C₅Me₅RhCl(SPPh₂)₂Pt(S₂CNEt₂)] (II) have been synthesised by reaction of NEt₂H₂[Pt(S₂CNEt₂)(Ph₂PS)₂] with either [M(η-arene)Cl₂]₂ or [Rh(η-C₅Me₅)Cl₂]₂ (2/1) molar ratio). Further reactions of I include facile chloride displacement with a range of neutral ligands L to give [η-areneML(SPPh₂)₂Pt(S₂CNEt₂)⁺ (III) cations and formation of tri- and penta-metallic species on treatment with more [Pt(S₂CNEt₂)(Ph₂PS)₂]^-.
