The structure described by Ce4IrCd crystallizes in the cubic F-43m space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) and three equivalent Cd(1) atoms. In the second Ce site, Ce(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ir(1) and two equivalent Cd(1) atoms. In the third Ce site, Ce(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 Ce(1), three equivalent Ce(2), and three equivalent Ce(3) atoms. Cd(1) is bonded to three equivalent Ce(1), three equivalent Ce(2), three equivalent Ce(3), and three equivalent Cd(1) atoms to form a mixture of distorted corner and face-sharing CdCe9Cd3 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
