The structure described by MgMn3SnO8 is beta indium sulfide-derived structured and crystallizes in the monoclinic C2/m space group. Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-18°. There are two 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 distorted MnO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-18°. In the second Mn site, Mn(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with two equivalent Sn(1)O6 octahedra. Sn(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form SnO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Mn(2)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mn(1), and two equivalent Mn(2) atoms. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mn(1), one Mn(2), and one Sn(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Mn(2) and one Sn(1) atom. is represented by the CIF file [CIF]
