Materials Data on BiSbWO6 by Materials Project

WBiSbO6 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 23–24°. There are a spread of W–O bond distances ranging from 1.88–2.07 Å. In the second W6+ site, W6+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 23–24°. There are a spread of W–O bond distances ranging from 1.87–2.08 Å. Bi3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.23–3.05 Å. Sb3+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Sb–O bond distances ranging from 2.04–2.77 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Bi3+ and two equivalent Sb3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Bi3+ and two equivalent Sb3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two W6+ and one Bi3+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two W6+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one W6+, one Bi3+, and one Sb3+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one W6+, one Bi3+, and one Sb3+ atom.
