In the fourth Mn site, Mn(4) is bonded to one O(2), one O(3), one O(4), one O(5), one O(6), and one F(1) atom to form MnO5F octahedra that share corners with two equivalent Mn(1)O5F octahedra, edges with two equivalent Mg(1)O5F octahedra, edges with two equivalent Mn(1)O5F octahedra, and edges with two equivalent Mn(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 18-19°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mg(1), one Mn(2), and one Mn(3) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mn(1), one Mn(2), and one Mn(4) atom.
