The material structure described by MgMn(SbO3)2 is Corundum-derived structured and crystallizes in the trigonal P312 space group. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share edges with three equivalent Sb(1)O6 octahedra, edges with three equivalent Sb(2)O6 octahedra, and faces with two equivalent Mn(1)O6 octahedra. Mn(1) is bonded to six equivalent O(1) atoms to form distorted MnO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra, corners with six equivalent Sb(2)O6 octahedra, and faces with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-54°. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, and edges with three equivalent Sb(2)O6 octahedra. The corner-sharing octahedral tilt angles are 39°. In the second Sb site, Sb(2) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, and edges with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. O(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mn(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
