MnOF is Hydrophilite-derived structured and crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), two equivalent F(1), and two equivalent F(2) atoms to form MnO2F4 octahedra that share corners with two equivalent Mn(1)O2F4 octahedra, corners with six equivalent Mn(2)O4F2 octahedra,  an edgeedge with one Mn(1)O2F4 octahedra, and  an edgeedge with one Mn(2)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 47-57°. In the second Mn site, Mn(2) is bonded to two equivalent O(1), two equivalent O(2), one F(1), and one F(2) atom to form MnO4F2 octahedra that share corners with two equivalent Mn(2)O4F2 octahedra, corners with six equivalent Mn(1)O2F4 octahedra,  an edgeedge with one Mn(1)O2F4 octahedra, and  an edgeedge with one Mn(2)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 47-57°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mn(1) and two equivalent Mn(2) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mn(1) and two equivalent Mn(2) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms.
