HoZnSn 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 12-coordinate geometry to six equivalent Zn(1) and six equivalent Sn(1) atoms. In the second Ho site, Ho(2) is bonded to six equivalent Sn(1) atoms to form edge-sharing HoSn6 octahedra. Zn(1) is bonded in a 6-coordinate geometry to three equivalent Ho(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and three equivalent Zn(1) atoms.
