The material described by Ho2CuIn3 crystallizes in the trigonal P3m1 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 9-coordinate geometry to three equivalent Cu(1), three equivalent In(1), three equivalent In(2), and three equivalent In(3) atoms. In the second Ho site, Ho(2) is bonded in a 6-coordinate geometry to three equivalent Cu(1), three equivalent In(1), three equivalent In(2), and three equivalent In(3) atoms. Cu(1) is bonded in a 10-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), one In(3), and three equivalent In(1) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), three equivalent Cu(1), and one In(2) atom. In the second In site, In(2) is bonded in a 10-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), one In(1), and three equivalent In(3) atoms. In the third In site, In(3) is bonded in a 10-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), one Cu(1), and three equivalent In(2) atoms. is represented by the CIF file [CIF]
