The material structure described by SmPdCd crystallizes in the hexagonal P-62m space group. Sm(1) is bonded in a 11-coordinate geometry to one Pd(2), four equivalent Pd(1), and six equivalent Cd(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(2) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Cd(1) atoms. In the second Pd site, Pd(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Cd(1) atoms. Cd(1) is bonded in a 10-coordinate geometry to six equivalent Sm(1), two equivalent Pd(1), and two equivalent Pd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
