The material structure described by MgMnO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Mg(1) is bonded to six equivalent O(1) atoms to form distorted MgO6 octahedra that share corners with nine equivalent Mn(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, and  a faceface with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-60°. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with nine equivalent Mg(1)O6 octahedra, edges with three equivalent Mn(1)O6 octahedra, and  a faceface with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-60°. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Mg(1) and two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
