The material described by CoFeO2 crystallizes in the hexagonal P6_3/mmc space group. Fe(1) is bonded to six equivalent O(1) atoms to form edge-sharing FeO6 octahedra. Co(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Fe(1) and one Co(1) atom to form a mixture of distorted edge and corner-sharing OFe3Co trigonal pyramids. is represented by the CIF card [CIF]
