Title: Materials Data on Li2VFeO4 by Materials Project

Abstract

Li2FeVO4 is alpha Po-derived structured and crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent FeO6 octahedra, edges with two equivalent FeO6 octahedra, edges with four equivalent VO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–5°. There are four shorter (2.17 Å) and two longer (2.21 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent VO6 octahedra, edges with two equivalent VO6 octahedra, edges with four equivalent FeO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedral tilt angles are 5°. All Li–O bond lengths are 2.18 Å. V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent VO6 octahedra, edges with four equivalent FeO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedral tilt angles are 5°. There are four shorter (2.04 Å) and two longer (2.11 Å) V–O bondmore » lengths. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent FeO6 octahedra, edges with four equivalent VO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–5°. There are four shorter (2.04 Å) and two longer (2.08 Å) Fe–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, two equivalent V3+, and one Fe3+ atom to form a mixture of edge and corner-sharing OLi3V2Fe octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to three Li1+, one V3+, and two equivalent Fe3+ atoms to form OLi3VFe2 octahedra that share corners with six equivalent OLi3VFe2 octahedra and edges with twelve OLi3V2Fe octahedra. The corner-sharing octahedral tilt angles are 0°.« less
