Title: Materials Data on LiFe2OF5 by Materials Project

Abstract

LiFe2OF5 is zeta iron carbide-derived 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 two O2- and four F1- atoms to form LiO2F4 octahedra that share corners with six FeOF5 octahedra and edges with three FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 50–57°. There are one shorter (2.06 Å) and one longer (2.07 Å) Li–O bond lengths. There are a spread of Li–F bond distances ranging from 2.06–2.09 Å. In the second Li1+ site, Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with six FeOF5 octahedra and edges with three FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 50–59°. There are a spread of Li–F bond distances ranging from 1.99–2.04 Å. In the third Li1+ site, Li1+ is bonded to one O2- and five F1- atoms to form LiOF5 octahedra that share corners with six FeOF5 octahedra and edges with three FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 46–59°. The Li–O bond length is 2.02 Å. There are a spread of Li–F bond distances ranging from 2.02–2.08 Å. There aremore » six inequivalent Fe3+ sites.
