Ruthenium(II) Complex Containing a New Hybrid Bidentate Phosphine–Thioether Ligand: [(p-Cymene)RuCl(Me₂PCH₂CH₂SMe)][BPh₄].0.5CH₂Cl₂

In the title compound, chloro­(η⁶-p-cymene)[1-(dimethylphosphino-P)-2-(methylthio-S)ethane]ruthenium(II) tetraphenylborate hemidichloromethane solvate, [RuCl(C₁₀H₁₄)(C₅H₁₃PS)][B(C₆H₅)₄].0.5CH₂Cl₂, the hybrid Me₂PCH₂CH₂SMe ligand is bidentate (κ²P,S), forming a five-membered chelate ring. The complex cation has two chiral centres, i.e. on the Ru and S atoms, and the relative configurations are R*(Ru)S*(S).
