Materials Data on W2O5 by Materials Project

Abstract

W2O5 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. W5+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 0–24°. There are a spread of W–O bond distances ranging from 1.90–2.14 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent W5+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two equivalent W5+ atoms. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to three equivalent W5+ atoms.
