Title: Materials Data on LiV(Si2O5)3 by Materials Project

Abstract

LiV(Si2O5)3 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (1.99 Å) and two longer (2.02 Å) Li–O bond lengths. V5+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six SiO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.82–1.95 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 a cornercorner with one VO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 36°. There is one shorter (1.62 Å) and three longer (1.63 Å) Si–O bond length. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one VO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 36°. There are a spread of Si–O bond distances ranging from 1.62–1.64 Å. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one VO6 octahedra and corners withmore » three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 35°. There are a spread of Si–O bond distances ranging from 1.62–1.64 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Si4+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. 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 bent 150 degrees geometry to two equivalent Si4+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one V5+, and one Si4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one V5+, and one Si4+ atom.« less
