Bis(trimethylphosphine-P)gold(I) hexafluorophosphate

U. E. I. Horvath and H. G. Raubenheimer

Abstract: The title compound, [Au(C₃H₉P)₂]PF₆, a linear two-coordinate gold(I) complex with coordinated trimethylphosphine ligands and hexafluorophosphate as counter-ion, is isomorphous with [Ag(Me₃P)₂]PF₆ and exhibits similar bond distances to [Au(Me₃P)₂]Cl, thus unconditionally substantiating previous comparisons and claims that the ionic radius of Au is smaller than that of Ag. The cation has mirror symmetry, so that the P-Au-P axis lies in this plane. Similarly, the anion has mirror symmetry, with the plane containing an F-P-F axis.
