Mn3(OF2)2 is Hydrophilite-derived structured and crystallizes in the orthorhombic Pnnm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1), one F(1), and three equivalent F(2) atoms to form a mixture of edge and corner-sharing MnO2F4 octahedra. The corner-sharing octahedral tilt angles range from 49-53°. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and four equivalent F(1) atoms to form a mixture of edge and corner-sharing MnO2F4 octahedra. The corner-sharing octahedral tilt angles range from 50-53°. O(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) 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(1) and two equivalent Mn(2) atoms. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to three equivalent Mn(1) atoms.

The corner-sharing octahedral tilt angles range from 49-53°. Both Mn(1)-O(1) bond lengths are 1.98 Å. The Mn(1)-F(1) bond length is 2.25 Å. There are two shorter (2.11 Å) and one longer (2.22 Å) Mn(1)-F(2) bond length. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and four equivalent F(1) atoms to form a mixture of edge and corner-sharing MnO2F4 octahedra. The corner-sharing octahedral tilt angles range from 50-53°. Both Mn(2)-O(1) bond lengths are 1.91 Å. All Mn(2)-F(1) bond lengths are 2.09 Å. O(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. There are two inequivalent F sites.
