The compound described by CoMnO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with nine equivalent Co(1)O6 octahedra, edges with three equivalent Mn(1)O6 octahedra, and  a faceface with one Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-59°. Co(1) is bonded to six equivalent O(1) atoms to form distorted CoO6 octahedra that share corners with nine equivalent Mn(1)O6 octahedra, edges with three equivalent Co(1)O6 octahedra, and  a faceface with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-59°. O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mn(1) and two equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
