Title: Materials Data on Li2V(Si2O5)3 by Materials Project

Abstract

Li2V(Si2O5)3 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 in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.57 Å. In the second Li1+ site, Li1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.33 Å. V4+ 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 1.86–2.08 Å. There are six inequivalent Si4+ sites.

In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and two Si4+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+ and two Si4+ atoms. In the ninth O2- site, O2- is bonded in a linear geometry to two Si4+ atoms.
