Title: Materials Data on W5O7 by Materials Project

Abstract

W5O7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are three inequivalent W+2.80+ sites. In the first W+2.80+ site, W+2.80+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 9°. There are a spread of W–O bond distances ranging from 2.12–2.32 Å. In the second W+2.80+ site, W+2.80+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 9°. There are two shorter (2.22 Å) and four longer (2.57 Å) W–O bond lengths. In the third W+2.80+ site, W+2.80+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 2.00–2.62 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent W+2.80+ atoms. In the second O2- site, O2- is bonded to six W+2.80+ atoms to form distorted OW6 octahedra that share corners with two equivalent OW6 octahedra, corners with two equivalent OW5 square pyramids, edges with five equivalent OW6 octahedra, and edges with five equivalent OW5 squaremore » pyramids. The corner-sharing octahedral tilt angles are 0°. In the third O2- site, O2- is bonded in a trigonal non-coplanar geometry to three W+2.80+ atoms. In the fourth O2- site, O2- is bonded to five W+2.80+ atoms to form distorted OW5 square pyramids that share corners with two equivalent OW6 octahedra, a cornercorner with one OW5 square pyramid, edges with five equivalent OW6 octahedra, and edges with two equivalent OW5 square pyramids. The corner-sharing octahedral tilt angles are 9°.« less
