Abstract

[Bis(trimethylsilyl)methyl](triphenylphosphine)gold(I) has been synthesized according to literature methods and its crystal structure determined. Treatment of this compound with [(Ph₃P)Au]₃O⁺BF₄⁻ in dichloromethane gives small amounts of the compound (Me₃Si)₂C[Au(PPh₃)₂]₂together with the novel trinuclear complex {(Me₃Si)₂C[Au(PPh₃)]₃}⁺BF₄⁻. The structure of the cation features the pentacoordinate carbon atom in a distorted-trigonal-bipyramidal environment with two silicon atoms in equatorial positions. Short axial/equatorial Au⋯Au contacts indicate peripheral metal-metal bonding.
