Title: Materials Data on LiFeF4 by Materials Project

Abstract

LiFeF4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with six FeF6 octahedra. The corner-sharing octahedra tilt angles range from 47–65°. There are a spread of Li–F bond distances ranging from 1.88–1.99 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six F1- atoms to form FeF6 octahedra that share corners with six equivalent LiF4 tetrahedra and edges with two equivalent FeF6 octahedra. There is two shorter (1.87 Å) and four longer (2.04 Å) Fe–F bond length. In the second Fe3+ site, Fe3+ is bonded to six F1- atoms to form FeF6 octahedra that share corners with six equivalent LiF4 tetrahedra and edges with two equivalent FeF6 octahedra. There are a spread of Fe–F bond distances ranging from 1.87–2.06 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Fe3+ atom. In the second F1- site, F1- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one Fe3+ atom. In the third F1- site, F1- ismore » bonded in a distorted trigonal planar geometry to one Li1+ and two Fe3+ atoms. In the fourth F1- site, F1- is bonded in a trigonal non-coplanar geometry to one Li1+ and two Fe3+ atoms.« less
