The structure described by V6O11F is Hydrophilite-derived structured and crystallizes in the monoclinic C2 space group. There are four inequivalent V sites. In the first V site, V(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms to form VO6 octahedra that share corners with two equivalent V(3)O5F octahedra, corners with six equivalent V(2)O6 octahedra, and edges with two equivalent V(4)O5F octahedra. The corner-sharing octahedral tilt angles range from 47-52°. In the second V site, V(2) is bonded to one O(1), one O(3), one O(4), one O(5), and two equivalent O(2) atoms to form VO6 octahedra that share corners with three equivalent V(1)O6 octahedra, corners with five equivalent V(4)O5F octahedra,  an edgeedge with one V(3)O5F octahedra, and  an edgeedge with one V(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-54°. In the third V site, V(3) is bonded to one O(6), two equivalent O(3), two equivalent O(4), and one F(1) atom to form VO5F octahedra that share corners with two equivalent V(1)O6 octahedra, corners with six equivalent V(4)O5F octahedra, and edges with two equivalent V(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-55°. In the fourth V site, V(4) is bonded to one O(1), one O(2), one O(4), one O(5), one O(6), and one F(1) atom to form VO5F octahedra that share corners with three equivalent V(3)O5F octahedra, corners with five equivalent V(2)O6 octahedra,  an edgeedge with one V(4)O5F octahedra, and  an edgeedge with one V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-55°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one V(1), one V(2), and one V(4) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one V(4) and two equivalent V(2) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one V(1), one V(2), and one V(3) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one V(2), one V(3), and one V(4) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one V(1), one V(2), and one V(4) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one V(3) and two equivalent V(4) atoms.
