  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.
