Materials Data on LiV(WO4)2 by Materials Project

Abstract

LiV(WO4)2 is zeta iron carbide-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with eight equivalent WO6 octahedra and edges with two equivalent VO6 octahedra. The corner-sharing octahedra tilt angles range from 50–56°. There are a spread of Li–O bond distances ranging from 2.16–2.22 Å. V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with eight equivalent WO6 octahedra and edges with two equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 42–54°. There are two shorter (2.04 Å) and four longer (2.05 Å) V–O bond lengths. W6+ is bonded to six O2- atoms to form distorted WO6 octahedra that share corners with four equivalent LiO6 octahedra, corners with four equivalent VO6 octahedra, and edges with two equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 42–56°. There are a spread of W–O bond distances ranging from 1.84–2.18 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V3+, and one W6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one V3+ and two equivalent W6+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one V3+, and one W6+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+ and two equivalent W6+ atoms.
