The Materials Project

CoAl2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Co2+ is bonded to four equivalent O2- atoms to form CoO4 tetrahedra that share corners with twelve equivalent AlO6 octahedra. The corner-sharing octahedral tilt angles are 60°. All Co–O bond lengths are 1.98 Å. Al3+ is bonded to six equivalent O2- atoms to form AlO6 octahedra that share corners with six equivalent CoO4 tetrahedra and edges with six equivalent AlO6 octahedra. All Al–O bond lengths are 1.93 Å. O2- is bonded to one Co2+ and three equivalent Al3+ atoms to form a mixture of distorted corner and edge-sharing OAl3Co tetrahedra.
