Abstract: The title compound, [Zr₂(C₅H₅)₄(C₁₆H₁₅PS)₂]·2CH₂Cl₂, was prepared by insertion of diphosphinoacetylene into the Zr-C bond of the transient (²-thioaldehyde)zirconocene formed by treatment of Cp₂ZrMe₂ with one equivalent of ethanediol. The sulfonium zirconocenate complex exhibits a centrosymmetric sulfur-bridged dimeric structure.
