Materials Data on La(AuF4)3 by Materials Project

Abstract

La(AuF4)3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. La3+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are three shorter (2.43 Å) and six longer (2.49 Å) La–F bond lengths. Au3+ is bonded in a square co-planar geometry to four F1- atoms. There are a spread of Au–F bond distances ranging from 1.94–1.99 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to one La3+ and one Au3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Au3+ atom. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to one La3+ and one Au3+ atom.
