Title: Materials Data on LiFe2F7 by Materials Project

Abstract

LiFe2F7 crystallizes in the monoclinic P2_1/m space group. The structure is two-dimensional and consists of one LiFe2F7 sheet oriented in the (1, 0, 0) direction. Li1+ is bonded in a see-saw-like geometry to four F1- atoms. There is three shorter (1.96 Å) and one longer (1.98 Å) Li–F bond length. Fe3+ is bonded to six F1- atoms to form a mixture of distorted edge and face-sharing FeF6 octahedra. There are a spread of Fe–F bond distances ranging from 1.85–2.05 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in an L-shaped geometry to two equivalent Fe3+ atoms. In the second F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Fe3+ atom. In the third F1- site, F1- is bonded in a water-like geometry to two equivalent Fe3+ atoms. In the fourth F1- site, F1- is bonded in a 3-coordinate geometry to one Li1+ and two equivalent Fe3+ atoms. In the fifth F1- site, F1- is bonded in a 3-coordinate geometry to one Li1+ and two equivalent Fe3+ atoms.
