Mn2O2F3 crystallizes in the monoclinic Cc space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), two equivalent O(2), one F(1), one F(2), and one F(3) atom to form a mixture of edge and corner-sharing MnO3F3 octahedra. The corner-sharing octahedral tilt angles range from 37-53°. In the second Mn site, Mn(2) is bonded to one O(2), two equivalent O(1), one F(1), one F(2), and one F(3) atom to form a mixture of edge and corner-sharing MnO3F3 octahedra. The corner-sharing octahedral tilt angles range from 37-55°. 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 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 water-like geometry to one Mn(1) and one Mn(2) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(2) atom. In the third F site, F(3) is bonded in a water-like geometry to one Mn(1) and one Mn(2) atom.
