Materials Data on Li2V3SnO8 by Materials Project
Li2V3SnO8 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 SnO6 octahedra and corners with nine VO6 octahedra. The corner-sharing octahedra tilt angles range from 51–62°. There are a spread of Li–O bond distances ranging from 1.98–2.06 Å. In the second Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.84–1.99 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 SnO6 octahedra, corners with three equivalent LiO4 tetrahedra, an edgeedge with one SnO6 octahedra, and edges with four VO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of V–O bond distances ranging from 1.90–2.11 Å. In the second V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent SnO6 octahedra, corners with three equivalent LiO4 tetrahedra, an edgeedge with one SnO6 octahedra, and edges with four VO6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of V–O bond distances ranging from 2.01–2.09 Å. In the third V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent SnO6 octahedra, corners with three equivalent LiO4 tetrahedra, an edgeedge with one SnO6 octahedra, and edges with four VO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of V–O bond distances ranging from 2.01–2.10 Å. Sn2+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six VO6 octahedra, corners with three equivalent LiO4 tetrahedra, and edges with three VO6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of Sn–O bond distances ranging from 2.06–2.18 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 Sn2+ atom. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, two V4+, and one Sn2+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two V4+, and one Sn2+ atom. In the fourth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three V4+ atoms. 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 Sn2+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two V4+, and one Sn2+ atom. In the eighth O2- site, O2- is bonded to one Li1+, two V4+, and one Sn2+ atom to form distorted corner-sharing OLiV2Sn tetrahedra.
