Materials Data on VP2O7 by Materials Project

Abstract

VO(PO3)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. V4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.63–2.01 Å. P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.61 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one V4+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one V4+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted linear geometry to one V4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent P5+ atoms.
