MgCo2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Mg(1) is bonded to four equivalent O(1) atoms to form MgO4 tetrahedra that share corners with twelve equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. Co(1) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Mg(1)O4 tetrahedra and edges with six equivalent Co(1)O6 octahedra. O(1) is bonded to one Mg(1) and three equivalent Co(1) atoms to form a mixture of distorted edge and corner-sharing OMgCo3 trigonal pyramids.
