description: Fe4O7F is Hydrophilite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Fe sites. In the first Fe site, Fe is bonded to five O and one F atom to form a mixture of corner and edge-sharing FeO5F octahedra. The corner-sharing octahedra tilt angles range from 47–52°. There are a spread of Fe–O bond distances ranging from 1.93–1.97 Å. The Fe–F bond length is 2.08 Å. In the second Fe site, Fe is bonded to five O and one F atom to form FeO5F octahedra that share corners with eight FeO5F octahedra and edges with two equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 48–52°. There are a spread of Fe–O bond distances ranging from 1.93–1.98 Å. The Fe–F bond length is 2.13 Å.
