The compound described by Fe4O5F3 is Hydrophilite-derived structured and crystallizes in the monoclinic Pc space group. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), one O(3), one O(4), one O(5), one F(1), and one F(3) atom to form FeO4F2 octahedra that share corners with two equivalent Fe(3)O3F3 octahedra, corners with two equivalent Fe(4)O4F2 octahedra, corners with four equivalent Fe(2)O4F2 octahedra,  an edgeedge with one Fe(3)O3F3 octahedra, and  an edgeedge with one Fe(4)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 44-58°. In the second Fe site, Fe(2) is bonded to one O(1), one O(2), one O(3), one O(5), one F(2), and one F(3) atom to form FeO4F2 octahedra that share corners with two equivalent Fe(3)O3F3 octahedra, corners with two equivalent Fe(4)O4F2 octahedra, corners with four equivalent Fe(1)O4F2 octahedra,  an edgeedge with one Fe(3)O3F3 octahedra, and  an edgeedge with one Fe(4)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 44-55°. In the third Fe site, Fe(3) is bonded to one O(1), one O(2), one O(4), one F(1), one F(2), and one F(3) atom to form a mixture of corner and edge-sharing FeO3F3 octahedra. The corner-sharing octahedral tilt angles range from 41-58°. In the fourth Fe site, Fe(4) is bonded to one O(2), one O(3), one O(4), one O(5), one F(1), and one F(2) atom to form FeO4F2 octahedra that share corners with two equivalent Fe(1)O4F2 octahedra, corners with two equivalent Fe(2)O4F2 octahedra, corners with four equivalent Fe(3)O3F3 octahedra,  an edgeedge with one Fe(1)O4F2 octahedra, and  an edgeedge with one Fe(2)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 41-57°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(3) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Fe(2), one Fe(3), and one Fe(4) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(4) atom.

In the first F site, F(1) is bonded in a trigonal planar geometry to one Fe(1), one Fe(3), and one Fe(4) atom. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Fe(2), one Fe(3), and one Fe(4) atom. In the third F site, F(3) is bonded in a trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
