Title: Materials Data on Li6Fe5O12 by Materials Project

Abstract

Li6Fe5O12 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are four inequivalent Li sites. In the first Li site, Li is bonded to six O atoms to form LiO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with four LiO6 octahedra, edges with five FeO6 octahedra, and edges with seven LiO6 octahedra. The corner-sharing octahedra tilt angles range from 1–11°. There are a spread of Li–O bond distances ranging from 2.01–2.42 Å. In the second Li site, Li is bonded to six O atoms to form LiO6 octahedra that share corners with two LiO6 octahedra, corners with three FeO6 octahedra, edges with five LiO6 octahedra, and edges with six FeO6 octahedra. The corner-sharing octahedra tilt angles range from 2–16°. There are a spread of Li–O bond distances ranging from 2.01–2.35 Å. In the third Li site, Li is bonded to six O atoms to form distorted LiO6 octahedra that share corners with two LiO6 octahedra, corners with three FeO6 octahedra, edges with five LiO6 octahedra, and edges with six FeO6 octahedra.
