Derivatives of Bis(diphenylphosphino)difluoromethane: the Disulfide Ph₂P(= S)CF₂P(= S)Ph₂ and the Bis[chlorogold(I)] Complex Ph₂P(AuCl)CF₂P(AuCl)Ph₂

The title compound difluoromethylenebis(diphenylphosphine) disulfide, C₂₅H₂₀F₂P₂S₂, displays an S1—P1...P2—S2 torsion angle of −90.76 (5)°. The P—CF₂ bond lengths of 1.893 (2) and 1.893 (3) Å are appreciably lengthened in comparison to systems involving the non-fluorinated analogue diphenylphosphinomethane. In the complex μ-[difluoromethylenebis(diphenylphosphine)-P,P']-bis[chlorogold(I)], [Au₂Cl₂(C₂₅H₂₀F₂P₂)], the Au—P...P—Au torsion angle is 31.2 (1)° and a short intramolecular Au...Au contact of 3.1432 (8) Å is observed.
