Mn3(OF2)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 two equivalent O(1), one F(1), one F(3), and two equivalent F(2) atoms to form a mixture of corner and edge-sharing MnO2F4 octahedra. The corner-sharing octahedral tilt angles range from 42-54°. In the second Mn site, Mn(2) is bonded to two equivalent O(1), one F(1), one F(3), and two equivalent F(2) atoms to form a mixture of corner and edge-sharing MnO2F4 octahedra. The corner-sharing octahedral tilt angles range from 42-54°. O(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a distorted T-shaped geometry to one Mn(2) and two equivalent Mn(1) atoms. In the third F site, F(3) is bonded in a trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms.
