Materials Data on V2O3 by Materials Project

Abstract

V2O3 crystallizes in the monoclinic Cc space group. The structure is two-dimensional and consists of two V2O3 sheets oriented in the (0, 0, 1) direction. there are two inequivalent V3+ sites. In the first V3+ site, V3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of V–O bond distances ranging from 1.79–1.87 Å. In the second V3+ site, V3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of V–O bond distances ranging from 1.77–1.85 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two V3+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two V3+ atoms. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two V3+ atoms.
