Title: Materials Data on Li3V5O12 by Materials Project

Abstract

Li3V5O12 is Ilmenite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share a cornercorner with one VO6 octahedra, corners with two equivalent LiO6 octahedra, corners with four equivalent LiO6 pentagonal pyramids, edges with three VO6 octahedra, and a faceface with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 59–61°. There are a spread of Li–O bond distances ranging from 2.02–2.19 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 pentagonal pyramids that share corners with four equivalent LiO6 octahedra, corners with five VO6 octahedra, edges with two equivalent VO6 octahedra, and a faceface with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 53–66°. There are a spread of Li–O bond distances ranging from 2.06–2.20 Å. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with seven VO6 octahedra, an edgeedge with one VO6 octahedra, and a faceface with one VO6 octahedra.

The corner-sharing octahedra tilt angles range from 36–64°. There are a spread of V–O bond distances ranging from 1.74–2.12 Å. In the fifth V+4.20+ site, V+4.20+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with two equivalent VO6 octahedra, corners with four equivalent LiO6 octahedra, corners with two equivalent LiO6 pentagonal pyramids, and edges with three VO6 octahedra. The corner-sharing octahedra tilt angles range from 53–64°. There are a spread of V–O bond distances ranging from 1.96–2.08 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded to one Li1+ and three V+4.20+ atoms to form a mixture of distorted edge and corner-sharing OLiV3 trigonal pyramids. In the second O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two V+4.20+ atoms. In the third O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two V+4.20+ atoms.
