Materials Data on Sb(WO3)5 by Materials Project

Abstract

Sb(WO3)5 crystallizes in the orthorhombic Cmme space group. The structure is three-dimensional. there are three inequivalent W+5.40+ sites. In the first W+5.40+ site, W+5.40+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 3–43°. There are a spread of W–O bond distances ranging from 1.91–2.11 Å. In the second W+5.40+ site, W+5.40+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 3–38°. There are a spread of W–O bond distances ranging from 1.92–2.03 Å. In the third W+5.40+ site, W+5.40+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 0–43°. There are a spread of W–O bond distances ranging from 1.85–2.09 Å. Sb3+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.11 Å) and two longer (2.75 Å) Sb–O bond lengths. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent W+5.40+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two W+5.40+ and one Sb3+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two W+5.40+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two W+5.40+ atoms. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two W+5.40+ atoms. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two W+5.40+ atoms. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two W+5.40+ and one Sb3+ atom.
