Title: Materials Data on Li2VO2F by Materials Project

Abstract

Li2VO2F is Caswellsilverite-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to three O2- and three F1- atoms to form LiO3F3 octahedra that share corners with six LiO3F3 octahedra, edges with five VO4F2 octahedra, and edges with seven LiO4F2 octahedra. The corner-sharing octahedra tilt angles range from 1–10°. There are one shorter (1.97 Å) and two longer (2.20 Å) Li–O bond lengths. There are one shorter (2.04 Å) and two longer (2.07 Å) Li–F bond lengths. In the second Li1+ site, Li1+ is bonded to four O2- and two F1- atoms to form LiO4F2 octahedra that share corners with six LiO3F3 octahedra, edges with five VO4F2 octahedra, and edges with seven LiO3F3 octahedra. The corner-sharing octahedra tilt angles range from 1–7°. There are a spread of Li–O bond distances ranging from 2.07–2.22 Å. There are one shorter (2.05 Å) and one longer (2.14 Å) Li–F bond lengths. In the third Li1+ site, Li1+ is bonded to five O2- and one F1- atom to form distorted LiO5F octahedra that share corners with two equivalent LiO5F octahedra, corners with four VO4F2 octahedra, edgesmore » with four VO4F2 octahedra, and edges with eight LiO3F3 octahedra. The corner-sharing octahedra tilt angles range from 0–15°. There are a spread of Li–O bond distances ranging from 2.03–2.17 Å. The Li–F bond length is 2.61 Å.

The corner-sharing octahedra tilt angles range from 0–16°. There are a spread of V–O bond distances ranging from 1.88–2.09 Å. The V–F bond length is 2.47 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to four Li1+ and two V3+ atoms to form OLi4V2 octahedra that share corners with six OLi4V2 octahedra, edges with five FLi4V2 octahedra, and edges with seven OLi3V3 octahedra.
