Title: Materials Data on LiVSi3O8 by Materials Project

Abstract

LiVSi3O8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. 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 2.00–2.24 Å. V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with five SiO4 tetrahedra, an edgeedge with one VO6 octahedra, and an edgeedge with one SiO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.98–2.28 Å. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent VO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–64°. There are a spread of Si–O bond distances ranging from 1.61–1.65 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one VO6 octahedra, corners with two SiO4 tetrahedra, and an edgeedge with one VO6 octahedra. The corner-sharing octahedral tilt angles are 43°. There are a spread of Si–O bond distances ranging from 1.61–1.69 Å. In the third Si4+ site, Si4+ is bonded to fourmore » O2- atoms to form SiO4 tetrahedra that share corners with two equivalent VO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 36–39°. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one V3+, and one Si4+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two Si4+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one V3+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent V3+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V3+, and one Si4+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one V3+ and two Si4+ atoms.« less
