The crystal structure described by CuGaO2 crystallizes in the trigonal R-3m space group. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. Ga(1) is bonded to six equivalent O(1) atoms to form edge-sharing GaO6 octahedra. O(1) is bonded to one Cu(1) and three equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing OGa3Cu trigonal pyramids. is represented by the CIF file [CIF]
