Abstract

The reaction of the potassium diketiminate K[RN=C(CF₃)CH=(CF₃)CNR)], where R = 3,5-C₆H₃Me₂, with PPh₃AuCl afford the complex [RN=C(CF₃)CH=(CF₃)CNR)AuPPh₃]. Unlike gold(I) diketiminates without backbone-CF₃ substituents, the complex is thermally stable in the solid state and in solution. The crystal structure confirms that, unlike previous examples of Au(I) ketiminates, this complex possesses a three-coordinate metal centre with a distorted Y-shaped coordination geometry.
