Materials Data on V2O5 by Materials Project

Abstract

V2O5 crystallizes in the monoclinic P2_1/m space group. The structure is two-dimensional and consists of one V2O5 sheet oriented in the (0, 0, 1) direction. there are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.60–2.36 Å. In the second V5+ site, V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.67–2.35 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three V5+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two V5+ atoms. In the third O2- site, O2- is bonded in a linear geometry to two V5+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to four V5+ atoms. In the fifth O2- site, O2- is bonded in a single-bond geometry to one V5+ atom.
