The synthesis and structural characterisation of the difluorido organo gold(III) complexes [AuClF₂(SIMes)] and [AuF₂(OTeF₅)(SIMes)] are presented. The substitution of a fluorido ligand in [AuF₃(SIMes)] by an OTeF₅ group increases the Lewis acidity of the Au moiety. A scale for carbene affinities is presented, which correlates calculated and experimental values for the Lewis acidity of the metal centre in akin compounds.
