Mn2O3F is Hydrophilite-derived structured and crystallizes in the monoclinic C2/m space group. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 50-51°. In the second Mn site, Mn(2) is bonded to four equivalent O(2) and two equivalent F(1) atoms to form MnO4F2 octahedra that share corners with eight equivalent Mn(3)O4F2 octahedra and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-51°. In the third Mn site, Mn(3) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent F(1) atoms to form MnO4F2 octahedra that share corners with four equivalent Mn(2)O4F2 octahedra, corners with four equivalent Mn(1)O6 octahedra, and edges with two equivalent Mn(3)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 46-51°. 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(3) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mn(1), one Mn(2), and one Mn(3) atom. F(1) is bonded in a distorted T-shaped geometry to one Mn(2) and two equivalent Mn(3) atoms.
