Raman scattering measurements indicate that cis-bridged chains are retained in AuF3 even at a compression of 45 GPa - in contrast to meta-GGA calculations suggesting that structures with such motifs are thermodynamically unstable above 4 GPa. This metastability implies that novel gold fluorides (e.g. AuF2) might be attainable at lower pressures than previously proposed.

压缩AuF3中顺式桥链的意外持久性。

拉曼散射测量表明，即使在45 GPa的压缩下，AuF3中仍保留了顺式桥连的链-与meta-GGA计算相反，这表明具有此类基序的结构在4 GPa以上是热力学不稳定的。这种亚稳定性表明，新型氟化金（例如AuF2）可以在比以前提出的更低的压力下获得。
