Mn3(O2F)2 is Hydrophilite-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent F(1) atoms to form a mixture of corner and edge-sharing MnO4F2 octahedra. The corner-sharing octahedral tilt angles range from 46-58°. In the second Mn site, Mn(2) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent F(1) atoms to form a mixture of corner and edge-sharing MnO4F2 octahedra. The corner-sharing octahedral tilt angles range from 49-58°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a distorted 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(2) and two equivalent Mn(1) atoms.
