Title: Materials Data on Li6V2O5F2 by Materials Project

Abstract

Li6V2O5F2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are six inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- and one F1- atom to form distorted LiO4F square pyramids that share corners with three equivalent VO4F2 octahedra, corners with four LiO4F square pyramids, a cornercorner with one LiO4F trigonal bipyramid, edges with three VO4F2 octahedra, and edges with five LiO4F square pyramids. The corner-sharing octahedra tilt angles range from 5–16°. There are a spread of Li–O bond distances ranging from 1.98–2.20 Å. The Li–F bond length is 2.25 Å. In the second Li1+ site, Li1+ is bonded to four O2- and one F1- atom to form LiO4F square pyramids that share corners with four LiO4F square pyramids, corners with four equivalent LiO4F trigonal bipyramids, edges with four VO4F2 octahedra, an edgeedge with one LiO4F square pyramid, and an edgeedge with one LiO4F trigonal bipyramid. There are a spread of Li–O bond distances ranging from 1.99–2.23 Å. The Li–F bond length is 2.18 Å. In the third Li1+ site, Li1+ is bonded in a 5-coordinate geometry to three O2- and two F1- atoms.
