Materials Data on CrCuO2 by Materials Project

CuCrO2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Cr3+ is bonded to six equivalent O2- atoms to form edge-sharing CrO6 octahedra. All Cr–O bond lengths are 2.03 Å. Cu1+ 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 Cr3+ and one Cu1+ atom to form a mixture of distorted edge and corner-sharing OCr3Cu tetrahedra.
