Ho(NiSb)2 crystallizes in the tetragonal P4/nmm space group. Ho(1) is bonded in a 16-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), four equivalent Sb(1), and four equivalent Sb(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent Sb(2) atoms. In the second Ni site, Ni(2) is bonded in a 5-coordinate geometry to four equivalent Ho(1), one Sb(2), and four equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 4-coordinate geometry to four equivalent Ho(1) and four equivalent Ni(2) atoms. In the second Sb site, Sb(2) is bonded in a 9-coordinate geometry to four equivalent Ho(1), one Ni(2), and four equivalent Ni(1) atoms.
