Materials Data on AuF3 by Materials Project
AuF3 crystallizes in the hexagonal P6_122 space group. The structure is one-dimensional and consists of one AuF3 ribbon oriented in the (0, 0, 1) direction. Au3+ is bonded in a distorted square co-planar geometry to four F1- atoms. There is two shorter (1.93 Å) and two longer (2.05 Å) Au–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 120 degrees geometry to two equivalent Au3+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one Au3+ atom.
