The compound described by CuCrO2 crystallizes in the hexagonal P6_3/mmc space group. Cr(1) is bonded to six equivalent O(1) atoms to form edge-sharing CrO6 octahedra. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Cr(1) and one Cu(1) atom to form a mixture of distorted corner and edge-sharing OCr3Cu tetrahedra. is represented by the CIF file [CIF]
