The compound described by Pr4PdCd crystallizes in the cubic F-43m space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 3-coordinate geometry to three equivalent Pd(1) and three equivalent Cd(1) atoms. In the second Pr site, Pr(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Pd(1) and two equivalent Cd(1) atoms. In the third Pr site, Pr(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 Pr(1), three equivalent Pr(2), and three equivalent Pr(3) atoms. Cd(1) is bonded to three equivalent Pr(1), three equivalent Pr(2), three equivalent Pr(3), and three equivalent Cd(1) atoms to form a mixture of distorted face and corner-sharing CdPr9Cd3 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
