Mn2AlO4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Al(1)O4 tetrahedra and edges with six equivalent Mn(1)O6 octahedra. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with twelve equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 55°. O(1) is bonded in a rectangular see-saw-like geometry to three equivalent Mn(1) and one Al(1) atom.
