FeAl2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Fe(1) is bonded to four equivalent O(1) atoms to form FeO4 tetrahedra that share corners with twelve equivalent Al(1)O6 octahedra. The corner-sharing octahedral tilt angles are 60°. Al(1) is bonded to six equivalent O(1) atoms to form AlO6 octahedra that share corners with six equivalent Fe(1)O4 tetrahedra and edges with six equivalent Al(1)O6 octahedra. O(1) is bonded to one Fe(1) and three equivalent Al(1) atoms to form a mixture of distorted corner and edge-sharing OAl3Fe tetrahedra.
