Materials Data on Sb2(AuF6)3 by Materials Project

Abstract

Sb2(AuF6)3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Sb2(AuF6)3 sheet oriented in the (1, 0, 0) direction. there are two inequivalent Au4+ sites. In the first Au4+ site, Au4+ is bonded in a distorted square co-planar geometry to four F1- atoms. There are two shorter (2.15 Å) and two longer (2.17 Å) Au–F bond lengths. In the second Au4+ site, Au4+ is bonded in a distorted rectangular see-saw-like geometry to four F1- atoms. There are a spread of Au–F bond distances ranging from 1.92–2.03 Å. Sb3+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Sb–F bond distances ranging from 1.89–2.09 Å. There are nine inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to one Au4+ and one Sb3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to one Sb3+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Au4+ atom. In the seventh F1- site, F1- is bonded in a bent 120 degrees geometry to two Au4+ atoms. In the eighth F1- site, F1- is bonded in a distorted bent 120 degrees geometry to two Au4+ atoms. In the ninth F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom.
