Materials Data on WO4 by Materials Project

Abstract

WO4 crystallizes in the orthorhombic Pnnm space group. The structure is zero-dimensional and consists of two WO4 clusters. there are two inequivalent W sites. In the first W site, W is bonded in a 6-coordinate geometry to six O atoms. There are a spread of W–O bond distances ranging from 1.76–2.34 Å. In the second W site, W is bonded in a 6-coordinate geometry to six O atoms. There are a spread of W–O bond distances ranging from 1.79–2.20 Å. There are five inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one W atom. In the second O site, O is bonded in a distorted T-shaped geometry to three W atoms. In the third O site, O is bonded in a single-bond geometry to one W atom. In the fourth O site, O is bonded in a bent 120 degrees geometry to two W atoms. In the fifth O site, O is bonded in a single-bond geometry to one W atom.
