The structure described by Fe4OF7 is Hydrophilite-derived structured and crystallizes in the monoclinic C2/c space group. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), one F(2), one F(3), one F(4), and two equivalent F(1) atoms to form FeOF5 octahedra that share corners with four equivalent Fe(3)F6 octahedra, corners with four equivalent Fe(2)OF5 octahedra, and edges with two equivalent Fe(1)OF5 octahedra. The corner-sharing octahedral tilt angles range from 44-54°. In the second Fe site, Fe(2) is bonded to one O(1), one F(2), two equivalent F(3), and two equivalent F(4) atoms to form FeOF5 octahedra that share corners with eight equivalent Fe(1)OF5 octahedra and edges with two equivalent Fe(3)F6 octahedra. The corner-sharing octahedral tilt angles range from 44-49°. In the third Fe site, Fe(3) is bonded to two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form a mixture of edge and corner-sharing FeF6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. O(1) is bonded in a distorted trigonal planar geometry to one Fe(2) and two equivalent Fe(1) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Fe(3) and two equivalent Fe(1) atoms. In the second F site, F(2) is bonded in a distorted T-shaped geometry to one Fe(2) and two equivalent Fe(1) atoms. In the third F site, F(3) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(3) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
