Ho5Ga3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 5-coordinate geometry to five equivalent Ga(1) atoms. In the second Ho site, Ho(2) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Ho(2) and five equivalent Ho(1) atoms.
Ho5Ga3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 5-coordinate geometry to five equivalent Ga(1) atoms. There are a spread of Ho(1)-Ga(1) bond distances ranging from 2.95-3.47 Å. In the second Ho site, Ho(2) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. All Ho(2)-Ga(1) bond lengths are 3.08 Å. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Ho(2) and five equivalent Ho(1) atoms.
