Materials Data on HAuO2 by Materials Project

Abstract

AuOOH crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Au3+ sites. In the first Au3+ site, Au3+ is bonded in a square co-planar geometry to four O2- atoms. All Au–O bond lengths are 2.03 Å. In the second Au3+ site, Au3+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.02 Å) and two longer (2.03 Å) Au–O bond lengths. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.15 Å) and one longer (1.28 Å) H–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Au3+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Au3+ and one H1+ atom.
