The structure described by Nd4IrCd crystallizes in the cubic F-43m space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) and three equivalent Cd(1) atoms. In the second Nd site, Nd(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ir(1) and two equivalent Cd(1) atoms. In the third Nd site, Nd(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 Nd(1), three equivalent Nd(2), and three equivalent Nd(3) atoms. Cd(1) is bonded to three equivalent Nd(1), three equivalent Nd(2), three equivalent Nd(3), and three equivalent Cd(1) atoms to form a mixture of face and corner-sharing CdNd9Cd3 cuboctahedra. is represented by the CIF file [CIF]
