CuGaO2 crystallizes in the hexagonal P6_3/mmc 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 edge and corner-sharing OGa3Cu trigonal pyramids.
CuGaO2 crystallizes in the hexagonal P6_3/mmc space group. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Cu(1)-O(1) bond lengths are 1.85 Å. Ga(1) is bonded to six equivalent O(1) atoms to form edge-sharing GaO6 octahedra. All Ga(1)-O(1) bond lengths are 1.99 Å. O(1) is bonded to one Cu(1) and three equivalent Ga(1) atoms to form a mixture of distorted edge and corner-sharing OGa3Cu trigonal pyramids.
