The material structure described by Fe4O7F is Hydrophilite-derived structured and crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), one O(2), one O(4), two equivalent O(3), and one F(1) atom to form FeO5F octahedra that share corners with four equivalent Fe(3)O5F octahedra, corners with four equivalent Fe(2)O6 octahedra, and edges with two equivalent Fe(1)O5F octahedra. The corner-sharing octahedral tilt angles range from 48-53°. In the second Fe site, Fe(2) is bonded to one O(1), one O(4), and four equivalent O(3) atoms to form a mixture of corner and edge-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. In the third Fe site, Fe(3) is bonded to one O(2), four equivalent O(3), and one F(1) atom to form FeO5F octahedra that share corners with eight equivalent Fe(1)O5F octahedra and edges with two equivalent Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Fe(2) and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Fe(3) and two equivalent Fe(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(3) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Fe(2) and two equivalent Fe(1) atoms. F(1) is bonded in a distorted trigonal planar geometry to one Fe(3) and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
