Mn3(O2F)2 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm 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 a mixture of edge and corner-sharing MnO4F2 octahedra. The corner-sharing octahedral tilt angles range from 45-54°. 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 45-54°. O(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. F(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms.

The corner-sharing octahedral tilt angles range from 45-54°. There are two shorter (1.90 Å) and two longer (2.01 Å) Mn(1)-O(1) bond lengths. Both Mn(1)-F(1) bond lengths are 2.05 Å. 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 45-54°. All Mn(2)-O(1) bond lengths are 1.98 Å. Both Mn(2)-F(1) bond lengths are 2.09 Å. O(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. F(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms.
