Title: Materials Data on LiVSiO5 by Materials Project

Abstract

LiVSiO5 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.00–2.66 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with four equivalent SiO4 tetrahedra, corners with two equivalent VO5 trigonal bipyramids, and edges with two equivalent VO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 46°. There are a spread of Li–O bond distances ranging from 2.14–2.62 Å. There are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with four equivalent SiO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.64–1.93 Å. In the second V5+ site, V5+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent LiO6 octahedra, corners with four equivalent SiO4 tetrahedra, and edges with two equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles rangemore » from 66–68°. There are a spread of V–O bond distances ranging from 1.63–1.90 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent LiO6 octahedra and corners with four VO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 65–68°. There is two shorter (1.64 Å) and two longer (1.65 Å) Si–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Li1+ and one V5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one V5+, and one Si4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V5+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one V5+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V5+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Li1+ and one V5+ atom.« less
