Title: Materials Data on Fe3(OF)2 by Materials Project

Abstract

Fe3(OF)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are twelve inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to two O2- and two F1- atoms to form FeO2F2 tetrahedra that share corners with six FeO4F2 octahedra and corners with two equivalent FeO2F2 tetrahedra. The corner-sharing octahedra tilt angles range from 57–73°. There is one shorter (1.96 Å) and one longer (1.97 Å) Fe–O bond length. Both Fe–F bond lengths are 2.13 Å. In the second Fe2+ site, Fe2+ is bonded to two O2- and two F1- atoms to form FeO2F2 tetrahedra that share corners with six FeO4F2 octahedra and corners with two equivalent FeO2F2 tetrahedra. The corner-sharing octahedra tilt angles range from 57–73°. There is one shorter (1.96 Å) and one longer (1.97 Å) Fe–O bond length. Both Fe–F bond lengths are 2.13 Å. In the third Fe2+ site, Fe2+ is bonded to four O2- and two F1- atoms to form distorted FeO4F2 octahedra that share corners with six FeO2F2 tetrahedra and edges with six FeO4F2 octahedra.
