title: Materials Data on Li2V3WO8 by Materials Project

description: Li2V3WO8 is Spinel-derived structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent WO6 octahedra and corners with nine VO6 octahedra. The corner-sharing octahedra tilt angles range from 57–62°. There are a spread of Li–O bond distances ranging from 2.00–2.02 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with three VO6 octahedra, corners with three equivalent WO6 octahedra, and edges with three VO6 octahedra. The corner-sharing octahedra tilt angles range from 61–62°. There are a spread of Li–O bond distances ranging from 1.81–2.04 Å. There are three inequivalent V4+ sites. In the first V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four LiO4 tetrahedra, an edgeedge with one WO6 octahedra, edges with four VO6 octahedra, and an edgeedge with one LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of V–O bond distances ranging from 1.99–2.15 Å. In the second V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four LiO4 tetrahedra, an edgeedge with one WO6 octahedra, edges with four VO6 octahedra, and an edgeedge with one LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–51°. There are a spread of V–O bond distances ranging from 1.99–2.10 Å. In the third V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four LiO4 tetrahedra, an edgeedge with one WO6 octahedra, edges with four VO6 octahedra, and an edgeedge with one LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 49–50°. There are a spread of V–O bond distances ranging from 1.99–2.14 Å. W2+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six VO6 octahedra, corners with six LiO4 tetrahedra, and edges with three VO6 octahedra. The corner-sharing octahedra tilt angles range from 49–51°. There are a spread of W–O bond distances ranging from 1.98–2.08 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, two V4+, and one W2+ atom. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, two V4+, and one W2+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two V4+, and one W2+ atom. In the fourth O2- site, O2- is bonded to one Li1+ and three V4+ atoms to form distorted corner-sharing OLiV3 trigonal pyramids. In the fifth O2- site, O2- is bonded to one Li1+ and three V4+ atoms to form distorted corner-sharing OLiV3 tetrahedra. In the sixth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, two V4+, and one W2+ atom. In the seventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two V4+, and one W2+ atom. In the eighth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two V4+, and one W2+ atom.
