The material structure described by HoGa3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to three equivalent Ga(1) and nine equivalent Ga(2) atoms to form a mixture of corner and face-sharing HoGa12 cuboctahedra. In the second Ho site, Ho(2) is bonded to six equivalent Ga(1) and six equivalent Ga(2) atoms to form a mixture of corner and face-sharing HoGa12 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), two equivalent Ga(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 12-coordinate geometry to one Ho(2), three equivalent Ho(1), two equivalent Ga(1), and six equivalent Ga(2) atoms. is represented by the CIF file [CIF]
