The material described by HoNi3Ga2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 18-coordinate geometry to three equivalent Ni(2), six equivalent Ni(1), three equivalent Ga(2), and six equivalent Ga(1) atoms. In the second Ho site, Ho(2) is bonded in a 18-coordinate geometry to six equivalent Ni(1), six equivalent Ni(2), and six equivalent Ga(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 10-coordinate geometry to one Ho(2), two equivalent Ho(1), one Ni(1), two equivalent Ni(2), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the second Ni site, Ni(2) is bonded to two equivalent Ho(1), two equivalent Ho(2), four equivalent Ni(1), two equivalent Ga(1), and two equivalent Ga(2) atoms to form a mixture of distorted corner and face-sharing NiHo4Ga4Ni4 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 6-coordinate geometry to four equivalent Ho(1), two equivalent Ni(2), and four equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded in a 6-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), two equivalent Ni(2), and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
