Materials Data on Sb2O3 by Materials Project

Abstract

Sb2O3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.00–2.60 Å. In the second Sb3+ site, Sb3+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 1.99–2.41 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Sb3+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to three Sb3+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three Sb3+ atoms.
