HfAuGa crystallizes in the hexagonal P-6m2 space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and six equivalent Ga(1) atoms. In the second Hf site, Hf(2) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Ga(1) atoms. Au(1) is bonded in a 10-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), one Au(1), and three equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), three equivalent Au(1), and one Ga(1) atom.
