The compound described by Ho2Co14Al3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 18-coordinate geometry to six equivalent Co(2) and twelve equivalent Co(3) atoms. In the second Ho site, Ho(2) is bonded in a 20-coordinate geometry to two equivalent Co(1), six equivalent Co(2), six equivalent Co(3), and six equivalent Al(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 14-coordinate geometry to one Ho(2), one Co(1), three equivalent Co(3), six equivalent Co(2), and three equivalent Al(1) atoms. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to one Ho(1), one Ho(2), two equivalent Co(1), two equivalent Co(2), four equivalent Co(3), and two equivalent Al(1) atoms. In the third Co site, Co(3) is bonded in a 12-coordinate geometry to one Ho(2), two equivalent Ho(1), one Co(1), two equivalent Co(3), four equivalent Co(2), and two equivalent Al(1) atoms. Al(1) is bonded in a 10-coordinate geometry to two equivalent Ho(2), two equivalent Co(1), four equivalent Co(2), and four equivalent Co(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
