Ho2NiSb4 crystallizes in the tetragonal P-4m2 space group. Ho(1) is bonded in a 11-coordinate geometry to two equivalent Ni(1), two equivalent Sb(1), two equivalent Sb(2), and five equivalent Sb(3) atoms. Ni(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ho(1) and four equivalent Sb(3) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent Sb(2) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent Sb(1) atoms. In the third Sb site, Sb(3) is bonded in a 7-coordinate geometry to five equivalent Ho(1) and two equivalent Ni(1) atoms.
