Ho6Co2In crystallizes in the orthorhombic Immm space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(2), and one In(1) atom. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to one Co(2), two equivalent Co(1), one In(1), and one In(2) atom. In the third Ho site, Ho(3) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), one In(1), and one In(2) atom. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(3), four equivalent Ho(2), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Ho(2), two equivalent Ho(3), four equivalent Ho(1), and one Co(2) atom. There are two inequivalent In sites. In the first In site, In(1) is bonded in a cuboctahedral geometry to four equivalent Ho(1), four equivalent Ho(2), and four equivalent Ho(3) atoms. In the second In site, In(2) is bonded in a body-centered cubic geometry to four equivalent Ho(2) and four equivalent Ho(3) atoms.
