The structure described by Fe6O11F is Hydrophilite-derived structured and crystallizes in the monoclinic C2 space group. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1), two equivalent O(4), and two equivalent O(6) atoms to form FeO6 octahedra that share corners with two equivalent Fe(3)O5F octahedra, corners with six equivalent Fe(2)O6 octahedra, and edges with two equivalent Fe(4)O5F octahedra. The corner-sharing octahedral tilt angles range from 47-51°. In the second Fe site, Fe(2) is bonded to one O(1), one O(2), one O(4), one O(6), and two equivalent O(3) atoms to form FeO6 octahedra that share corners with three equivalent Fe(1)O6 octahedra, corners with five equivalent Fe(4)O5F octahedra,  an edgeedge with one Fe(3)O5F octahedra, and  an edgeedge with one Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-52°. In the third Fe site, Fe(3) is bonded to one O(5), two equivalent O(2), two equivalent O(4), and one F(1) atom to form FeO5F octahedra that share corners with two equivalent Fe(1)O6 octahedra, corners with six equivalent Fe(4)O5F octahedra, and edges with two equivalent Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-54°. In the fourth Fe site, Fe(4) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and one F(1) atom to form FeO5F octahedra that share corners with three equivalent Fe(3)O5F octahedra, corners with five equivalent Fe(2)O6 octahedra,  an edgeedge with one Fe(4)O5F octahedra, and  an edgeedge with one Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-54°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(4) atom. In the second O site, O(2) is bonded in a 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 trigonal planar geometry to one Fe(4) and two equivalent Fe(2) atoms. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(3) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Fe(3) and two equivalent Fe(4) atoms. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(4) atom.
