The material structure described by Ho4NiMg crystallizes in the cubic F-43m space group. Mg(1) is bonded to three equivalent Mg(1), three equivalent Ho(1), three equivalent Ho(2), and three equivalent Ho(3) atoms to form a mixture of face and corner-sharing MgHo9Mg3 cuboctahedra. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to three equivalent Mg(1), three equivalent Ho(3), and three equivalent Ni(1) atoms. In the second Ho site, Ho(2) is bonded in a bent 150 degrees geometry to two equivalent Mg(1), four equivalent Ho(3), and two equivalent Ni(1) atoms. In the third Ho site, Ho(3) is bonded in a 14-coordinate geometry to two equivalent Mg(1), two equivalent Ho(1), four equivalent Ho(2), four equivalent Ho(3), and two equivalent Ni(1) atoms. Ni(1) is bonded in a 6-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and three equivalent Ho(3) atoms. is represented by the CIF card [CIF]
