Materials Data on Au2Se3O10 by Materials Project

Abstract

Au2Se3O10 crystallizes in the orthorhombic Cmc2_1 space group. The structure is two-dimensional and consists of two Au2Se3O10 sheets oriented in the (0, 0, 1) direction. Au5+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Au–O bond distances ranging from 2.02–2.04 Å. There are two inequivalent Se+3.33+ sites. In the first Se+3.33+ site, Se+3.33+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.64 Å) and two longer (1.76 Å) Se–O bond length. In the second Se+3.33+ site, Se+3.33+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.74 Å) and two longer (1.76 Å) Se–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Au5+ and one Se+3.33+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Au5+ and one Se+3.33+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Au5+ and one Se+3.33+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Se+3.33+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Au5+ and one Se+3.33+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Se+3.33+ atom.
