| Abstract: | Treatment of [(p-cymene)RuCl2]2 with HSp-Tol or HSCH2Ph in the presence of K[PF6] gave the cationic dinuclear cymene–ruthenium(II) complexes [(p-cymene)2Ru2(μ-Cl)(μ-Sp-Tol)2][PF6] (1) and [(p-cymene)2Ru2(μ-Cl)(μ-SCH2Ph)2][PF6] (2), respectively, which have been characterized by IR, NMR spectroscopies and mass spectrometry along with microanalyses. Their crystal structures were determined by single-crystal X-ray diffraction analyses. The structures of the cationic complexes contain the unusual pseudo-trigonal-bipyramidal Ru2S2Cl framework without a ruthenium–ruthenium single bond. The two p-cymene–ruthenium units are held together by two bridging thiolates and one bridging chloride. |
