MnOF is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to four equivalent O(1) and two equivalent F(1) atoms to form MnO4F2 octahedra that share corners with eight equivalent Mn(2)O2F4 octahedra and edges with two equivalent Mn(1)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 48-51°. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and four equivalent F(1) atoms to form MnO2F4 octahedra that share corners with eight equivalent Mn(1)O4F2 octahedra and edges with two equivalent Mn(2)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 48-51°. O(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. F(1) is bonded in a distorted trigonal planar geometry to one Mn(1) and two equivalent Mn(2) atoms.

In the second Mn site, Mn(2) is bonded to two equivalent O(1) and four equivalent F(1) atoms to form MnO2F4 octahedra that share corners with eight equivalent Mn(1)O4F2 octahedra and edges with two equivalent Mn(2)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 48-51°. Both Mn(2)-O(1) bond lengths are 1.89 Å. All Mn(2)-F(1) bond lengths are 2.05 Å. O(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. F(1) is bonded in a distorted trigonal planar geometry to one Mn(1) and two equivalent Mn(2) atoms.
