Title: Materials Data on Li2TiFeO4 by Materials Project

Abstract

Li2FeTiO4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one FeO6 octahedra, corners with five LiO6 octahedra, edges with four TiO6 octahedra, edges with four equivalent FeO6 octahedra, and edges with four LiO5 square pyramids. The corner-sharing octahedra tilt angles range from 1–4°. There are a spread of Li–O bond distances ranging from 2.03–2.16 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one FeO6 octahedra, corners with five LiO6 octahedra, corners with four LiO5 square pyramids, edges with four TiO6 octahedra, and edges with four equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 4–22°. There are a spread of Li–O bond distances ranging from 2.04–2.27 Å. In the third Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with two equivalent LiO6 octahedra, corners with two equivalent FeO6 octahedra, corners with five LiO5 square pyramids, edges with two equivalent LiO6 octahedra, edges with two equivalentmore » FeO6 octahedra, and edges with four equivalent TiO6 octahedra.
