The crystal structure described by AuCuO2 crystallizes in the trigonal R-3m space group. Au(1) is bonded in a linear geometry to two equivalent O(1) atoms. Cu(1) is bonded to six equivalent O(1) atoms to form edge-sharing CuO6 octahedra. O(1) is bonded to one Au(1) and three equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing OCu3Au tetrahedra. is represented by the CIF file [CIF]
