AuGa3 crystallizes in the hexagonal P6_3/mmc space group. Au(1) is bonded to twelve equivalent Ga(1) atoms to form a mixture of corner and face-sharing AuGa12 cuboctahedra. Ga(1) is bonded in a 2-coordinate geometry to four equivalent Au(1) atoms.
AuGa3 crystallizes in the hexagonal P6_3/mmc space group. Au(1) is bonded to twelve equivalent Ga(1) atoms to form a mixture of corner and face-sharing AuGa12 cuboctahedra. There are six shorter (2.81 Å) and six longer (3.15 Å) Au(1)-Ga(1) bond lengths. Ga(1) is bonded in a 2-coordinate geometry to four equivalent Au(1) atoms.
