Mn2O3F is Hydrophilite-derived structured and crystallizes in the monoclinic C2/m space group. There are four inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), four equivalent O(3), and one F(1) atom to form MnO5F octahedra that share corners with eight equivalent Mn(4)O4F2 octahedra and edges with two equivalent Mn(1)O5F octahedra. The corner-sharing octahedral tilt angles range from 45-52°. In the second Mn site, Mn(2) is bonded to two equivalent O(2) and four equivalent O(4) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. In the third Mn site, Mn(3) is bonded to four equivalent O(4) and two equivalent F(2) atoms to form MnO4F2 octahedra that share corners with eight equivalent Mn(4)O4F2 octahedra and edges with two equivalent Mn(2)O6 octahedra.
