Ho4IrCd crystallizes in the cubic F-43m space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) and three equivalent Cd(1) atoms. In the second Ho site, Ho(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ir(1) and two equivalent Cd(1) atoms. In the third Ho site, Ho(3) is bonded in a 4-coordinate geometry to two equivalent Ir(1) and two equivalent Cd(1) atoms. Ir(1) is bonded in a 6-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and three equivalent Ho(3) atoms. Cd(1) is bonded to three equivalent Ho(1), three equivalent Ho(2), three equivalent Ho(3), and three equivalent Cd(1) atoms to form a mixture of distorted corner and face-sharing CdHo9Cd3 cuboctahedra.
