Materials Data on Mg(AuF4)2 by Materials Project

Abstract

Mg(AuF4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mg2+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Mg–F bond distances ranging from 2.02–2.05 Å. 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 four inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one Au3+ atom. In the second F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one Au3+ atom. In the third F1- site, F1- is bonded in a bent 120 degrees geometry to one Mg2+ and one Au3+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Au3+ atom.
