摘要:
The reaction of the potassium diketiminate K[RN=C(CF3)CH=(CF3)CNR)], where R = 3,5-C6H3Me2, with PPh3AuCI 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 threecoordinate metal centre with a distorted Y-shaped coordination geometry.
