Fe2O3F is Hydrophilite-derived structured and crystallizes in the orthorhombic Imma space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), four equivalent O(2), and one F(1) atom to form FeO5F octahedra that share corners with eight equivalent Fe(2)O4F2 octahedra and edges with two equivalent Fe(1)O5F octahedra. The corner-sharing octahedral tilt angles range from 47-51°. In the second Fe site, Fe(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent F(1) atoms to form FeO4F2 octahedra that share corners with eight equivalent Fe(1)O5F octahedra and edges with two equivalent Fe(2)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 47-51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Fe(1) and two equivalent Fe(2) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Fe(2) and two equivalent Fe(1) atoms. F(1) is bonded in a 3-coordinate geometry to one Fe(1) and two equivalent Fe(2) atoms.
