In all cases, dicationic products of the type [Pt₂(μ-S)₂(PPh₃)₄ML]²⁺ (L=π-hydrocarbon ligand) are observed, and a number of complexes have been prepared on the synthetic scale, isolated as their BPh₄− or PF₆− salts, and fully characterised. A single-crystal X-ray structure determination on the Ru p-cymene derivative confirms the presence of a pseudo-five-coordinate Ru centre. This resists addition of small donor ligands such as CO and pyridine. The reaction of [Pt₂(μ-S)₂(PPh₃)₄] with RuClCp(PPh₃)₂ (Cp=η⁵-C₅H₅) gives [Pt₂(μ-S)₂(PPh₃)₄RuCp]⁺. In addition, the reaction of [Pt₂(μ-S)₂(PPh₃)₄] with the related carbonyl complex [RuCl₂(CO)₃]₂, monitored by electrospray mass spectrometry, gives [Pt₂(μ-S)₂(PPh₃)₄Ru(CO)₃Cl]⁺.enThis article is published in the Journal of Organometallic Chemistry, (c) 2003 Elsevier Science B.V.mixed-metal complexessulfide ligandselectrospray mass spectrometryplatinum complexesorganometallic complexesCoordination chemistry of the [Pt₂(μ-S)₂(PPh₃)₄] metalloligand with π-hydrocarbon derivatives of d⁶ ruthenium(II), osmium(II), rhodium(III) and iridium(III)Journal Article10.1016/S0022-328X(03)00464-9
