The compound described by Y4IrCd crystallizes in the cubic F-43m space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) and three equivalent Cd(1) atoms. In the second Y site, Y(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ir(1) and two equivalent Cd(1) atoms. In the third Y site, Y(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 Y(1), three equivalent Y(2), and three equivalent Y(3) atoms. Cd(1) is bonded to three equivalent Y(1), three equivalent Y(2), three equivalent Y(3), and three equivalent Cd(1) atoms to form a mixture of distorted face and corner-sharing CdY9Cd3 cuboctahedra. is represented by the CIF file [CIF]
