Materials Data on Fe4O7F by Materials Project
Fe4O7F is Hydrophilite-derived structured and crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with eight FeO6 octahedra and edges with two equivalent FeO5F octahedra. The corner-sharing octahedra tilt angles range from 48–53°. There are a spread of Fe–O bond distances ranging from 1.94–2.09 Å. In the second Fe site, Fe is bonded to five O and one F atom to form a mixture of edge and corner-sharing FeO5F octahedra. The corner-sharing octahedra tilt angles range from 47–52°. There is four shorter (1.94 Å) and one longer (1.97 Å) Fe–O bond length. The Fe–F bond length is 2.12 Å. In the third Fe site, Fe is bonded to five O and one F atom to form FeO5F octahedra that share corners with eight FeO6 octahedra and edges with two equivalent FeO5F octahedra. The corner-sharing octahedra tilt angles range from 47–54°. There are a spread of Fe–O bond distances ranging from 1.94–1.98 Å. The Fe–F bond length is 2.09 Å. In the fourth Fe site, Fe is bonded to five O and one F atom to form FeO5F octahedra that share corners with eight FeO6 octahedra and edges with two equivalent FeO5F octahedra. The corner-sharing octahedra tilt angles range from 47–54°. There are a spread of Fe–O bond distances ranging from 1.94–2.02 Å. The Fe–F bond length is 2.05 Å. There are seven inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to three Fe atoms. In the second O site, O is bonded in a trigonal planar geometry to three Fe atoms. In the third O site, O is bonded in a distorted trigonal planar geometry to three Fe atoms. In the fourth O site, O is bonded in a trigonal planar geometry to three Fe atoms. In the fifth O site, O is bonded in a distorted trigonal planar geometry to three Fe atoms. In the sixth O site, O is bonded in a trigonal planar geometry to three Fe atoms. In the seventh O site, O is bonded in a trigonal planar geometry to three Fe atoms. F is bonded in a distorted trigonal planar geometry to three Fe atoms.
