报道了[NMe_4][AuF_4]和[NEt_4][AuF_4]的合成，以及Cs[AuF_4]的改进的一锅法合成。新的[AuF 4]（-）盐的结构通过单晶X-射线衍射、NMR光谱、振动光谱和质谱进行表征。这些盐是第一种可以以纯形式分离的氟化金（III）盐，并且便于在常规有机溶剂中用于随后的合成。进一步报道了AuF_3分子配合物在溶液中的形成，其特征在于在低温下为[F_3Au（NCCH_3）]，在室温下为稳定的[F_3Au（py）]和双核衍生物。考察了它们在常用有机溶剂中的稳定性，结果表明它们具有较好的稳定性。
The synthesis of [NMe4][AuF4] and [NEt4][AuF4], as well as an improved one-pot synthesis of Cs[AuF4], is reported. The new [AuF4](-) salts were structurally characterized by single crystal X-ray diffraction, NMR spectroscopy, vibrational spectroscopy, and mass spectrometry. These salts are the first gold(III) fluoride salts that can be isolated in pure form and are convenient to be used in usual organic solvents for subsequent synthesis. The formation of molecular AuF3 complexes in solution is further reported, characterized as [F3Au(NCCH3)] at low temperature, as [F3Au(py)] and a binuclear derivative which are stable at room temperature. The stability of these species in common organic solvents was investigated and they showed a satisfying stability.
