The material described by LiAlMnO4 is Spinel-derived structured and crystallizes in the tetragonal P4_322 space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Al(1)O4 tetrahedra, edges with two equivalent Li(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Al(1)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Li(1)O6 octahedra. Al(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form AlO4 tetrahedra that share corners with six equivalent Li(1)O6 octahedra and corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-60°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1), one Mn(1), and one Al(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Mn(1), and one Al(1) atom. is represented by the CIF file [CIF]
