The compound described by CoMn2O4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra and edges with six equivalent Mn(1)O6 octahedra. Co(1) is bonded to four equivalent O(1) atoms to form CoO4 tetrahedra that share corners with twelve equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-58°. O(1) is bonded to three equivalent Mn(1) and one Co(1) atom to form a mixture of distorted edge and corner-sharing OMn3Co trigonal pyramids. is represented by the CIF card [CIF]
