Exopolyhedral Cyclized Platinaundecaboranes: [(PPh₃)(PhCOS)PtB₁₀H₁₁].0.5CH₂Cl₂

The asymmetric unit of the title compound 7,11- or 7,8-(μ-thiobenzoato-S:O)-7-(triphenylphosphine-P)-8,9:10,11-di-μH– 7-platina-nido-undecaborane–dichloromethane (1/0.5), C₂₅H₃₁B₁₀OPPtS.0.5CH₂Cl₂, contains two metallaborane molecules, which are approximate geometric isomers, and one molecule of dichloromethane solvent. Each isomer has an exopolyhedral thiobenzoate ligand bridging one Pt and one B atom to give a five-membered Pt–S–C–O–B ring.
