Materials Data on FeCoO2 by Materials Project
CoFeO2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Fe2+ is bonded to six equivalent O2- atoms to form edge-sharing FeO6 octahedra. There is two shorter (1.99 Å) and four longer (2.00 Å) Fe–O bond length. Co2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Co–O bond lengths are 1.84 Å. O2- is bonded to three equivalent Fe2+ and one Co2+ atom to form a mixture of distorted edge and corner-sharing OFe3Co trigonal pyramids.
