HfCuGa crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded to six equivalent Cu(1) and six equivalent Ga(1) atoms to form a mixture of face and edge-sharing HfGa6Cu6 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Ga(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Cu(1) atoms.
