Sm4PdCd crystallizes in the cubic F-43m space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 3-coordinate geometry to three equivalent Pd(1) and three equivalent Cd(1) atoms. In the second Sm site, Sm(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Pd(1) and two equivalent Cd(1) atoms. In the third Sm site, Sm(3) is bonded in a 4-coordinate geometry to two equivalent Pd(1) and two equivalent Cd(1) atoms. Pd(1) is bonded in a 6-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), and three equivalent Sm(3) atoms. Cd(1) is bonded to three equivalent Sm(1), three equivalent Sm(2), three equivalent Sm(3), and three equivalent Cd(1) atoms to form a mixture of distorted face and corner-sharing CdSm9Cd3 cuboctahedra.
