Materials Data on LiSbWO6 by Materials Project

Abstract

LiSbWO6 crystallizes in the tetragonal P4_122 space group. The structure is three-dimensional. Li1+ is bonded in a hexagonal planar geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.47–2.61 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with two equivalent WO6 octahedra and corners with four equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 34–44°. There is two shorter (1.93 Å) and four longer (1.94 Å) W–O bond length. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra and corners with four equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 42–50°. There is two shorter (1.99 Å) and four longer (2.00 Å) Sb–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+ and two equivalent Sb5+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent W6+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one W6+, and one Sb5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one W6+, and one Sb5+ atom.
