The structure described by Ho4Co3 crystallizes in the trigonal P-3 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 7-coordinate geometry to two equivalent Co(1) and five equivalent Co(2) atoms. In the second Ho site, Ho(2) is bonded in a 4-coordinate geometry to one Co(3) and three equivalent Co(2) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to six equivalent Ho(1) and three equivalent Co(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Ho(2), five equivalent Ho(1), and one Co(1) atom. In the third Co site, Co(3) is bonded in a 6-coordinate geometry to six equivalent Ho(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
