Materials Data on V2O5 by Materials Project

Abstract

V2O5 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two V2O5 sheets oriented in the (-1, 0, 1) direction. there are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form corner-sharing VO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.64–1.80 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form corner-sharing VO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.63–1.83 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two V5+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms.
