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.
稳定的二氟合金（III）配合物可以通过使用 XeF2 氧化 N 配位的阳离子金（I）前体，或者通过使用经济的 KF 中的氟离子从三价金（III）前体取代 N 配体来轻松合成。双咪唑配体衍生物的 X 射线晶体学研究表明，该配合物中存在已知最短的金-氟键。
