Materials Data on CoCuO2 by Materials Project
CuCoO2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Co2+ is bonded to six equivalent O2- atoms to form edge-sharing CoO6 octahedra. All Co–O bond lengths are 1.92 Å. Cu2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.85 Å. O2- is bonded to three equivalent Co2+ and one Cu2+ atom to form a mixture of distorted edge and corner-sharing OCo3Cu trigonal pyramids.
