Well defined difluorogold(iii) complexes supported by N-ligands

Abstract

Stable difluorogold(III) complexes can be easily synthesized either via oxidation of N-ligated cationic Au(I) precursors using XeF₂ or from tricationic Au(III) precursors by displacement of the N-ligands using fluoride from economical KF. X-ray crystallographic studies of the bisimidazole ligated derivative shows the shortest Au–F bond known in a gold complex.
