Materials Data on Bi2Se3O10 by Materials Project
Bi2Se3O10 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Bi5+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.25–2.89 Å. There are two inequivalent Se+3.33+ sites. In the first Se+3.33+ site, Se+3.33+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.72–1.79 Å. In the second Se+3.33+ site, Se+3.33+ is bonded in a tetrahedral geometry to four O2- atoms. All Se–O bond lengths are 1.68 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Bi5+ and one Se+3.33+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Bi5+ and one Se+3.33+ atom. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Bi5+ and one Se+3.33+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Bi5+ and one Se+3.33+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Bi5+ and one Se+3.33+ atom.
