Title: Materials Data on ZnW5O7 by Materials Project

Abstract

W5ZnO7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are three inequivalent W+2.40+ sites. In the first W+2.40+ site, W+2.40+ is bonded to six O2- atoms to form edge-sharing WO6 octahedra. There are a spread of W–O bond distances ranging from 2.12–2.45 Å. In the second W+2.40+ site, W+2.40+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 2.11–2.67 Å. In the third W+2.40+ site, W+2.40+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All W–O bond lengths are 2.53 Å. Zn2+ is bonded in a see-saw-like geometry to four O2- atoms. There are two shorter (2.04 Å) and two longer (2.18 Å) Zn–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to four W+2.40+ and one Zn2+ atom to form distorted OZnW4 trigonal bipyramids that share a cornercorner with one OZnW4 trigonal bipyramid, edges with two equivalent OZn2W2 tetrahedra, and edges with two equivalent OZnW4 trigonal bipyramids. In the second O2- site, O2- is bonded to two equivalent W+2.40+ and two equivalent Zn2+ atoms to form OZn2W2 tetrahedra that share corners withmore » two equivalent OZn2W2 tetrahedra and edges with four equivalent OZnW4 trigonal bipyramids. In the third O2- site, O2- is bonded in a 6-coordinate geometry to six W+2.40+ atoms. In the fourth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three W+2.40+ atoms.« less
