Mn3(O2F)2 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), three equivalent O(2), and two equivalent F(1) atoms to form a mixture of edge and corner-sharing MnO4F2 octahedra. The corner-sharing octahedral tilt angles range from 45-52°. In the second Mn site, Mn(2) is bonded to four equivalent O(1) and two equivalent F(1) atoms to form a mixture of edge and corner-sharing MnO4F2 octahedra. The corner-sharing octahedral tilt angles range from 52-53°. 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 three equivalent Mn(1) atoms. F(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms.
