MgMnO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to twelve equivalent O(1) atoms to form MgO12 cuboctahedra that share corners with twelve equivalent Mg(1)O12 cuboctahedra, faces with six equivalent Mg(1)O12 cuboctahedra, and faces with eight equivalent Mn(1)O6 octahedra. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra and faces with eight equivalent Mg(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Mg(1) and two equivalent Mn(1) atoms.
