Derivatives of Bis(diphenylphosphino)difluoromethane: the Disulfide Ph2P(= S)CF2P(= S)Ph2 and the Bis[chlorogold(I)] Complex Ph2P(AuCl)CF2P(AuCl)Ph2
摘要:
The title compound difluoromethylenebis (diphenylphosphine) disulfide, C25H20F2P2S2, displays an S1-P1 P1 ... P2-S2 torsion angle of -90.76(5)degrees. The P-CF2 bond lengths of 1.893(2) and 1.893(3)Angstrom are appreciably lengthened in comparison with systems involving the non-fluorinated analogue diphenylphosphinomethane. In the title complex mu-[difluoromethylenebis (diphenylphosphine)-P,P'] -bis [chlorogold(I)], [AU(2)Cl(2)(C25H20F2P2)], the Au-P ... P-Au torsion angle is 31.2(1)degrees and a short intramolecular Au ... Au contact of 3.1432(8)Angstrom is observed.
