Materials Data on Li3V2(O2F)2 by Materials Project
Abstract
Li3V2(O2F)2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to three O2- and three F1- atoms to form distorted LiO3F3 octahedra that share corners with three equivalent LiO3F3 octahedra, corners with three equivalent VO6 octahedra, edges with three VO6 octahedra, and edges with six LiO3F3 octahedra. The corner-sharing octahedra tilt angles range from 0–16°. There are a spread of Li–O bond distances ranging from 2.33–2.44 Å. There is one shorter (1.92 Å) and two longer (2.00 Å) Li–F bond length. In the second Li1+ site, Li1+ is bonded to three O2- and three F1- atoms to form distorted LiO3F3 octahedra that share corners with two equivalent LiO3F3 octahedra, corners with three equivalent VO6 octahedra, edges with three VO6 octahedra, and edges with six equivalent LiO3F3 octahedra. The corner-sharing octahedra tilt angles range from 0–16°. There are one shorter (2.31 Å) and two longer (2.45 Å) Li–O bond lengths. There is two shorter (1.91 Å) and one longer (1.93 Å) Li–F bond length. There are two inequivalent V+3.50+ sites. In the first V+3.50+ site, V+3.50+ is bonded to six O2- atoms to form VO6more »

In the second F1- site, F1- is bonded to five Li1+ atoms to form FLi5 trigonal bipyramids that share corners with three equivalent OLi3V3 octahedra, corners with four OLi2V3 square pyramids, an edgeedge with one OLi3V3 octahedra, edges with three OLi2V3 square pyramids, and edges with two equivalent FLi5 trigonal bipyramids.
