Bis(trimethylphosphine-κP)gold(I) hexafluorophosphate

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.
