The compound described by Ce8Pd24Sn crystallizes in the cubic Pm-3m space group. Ce(1) is bonded to three equivalent Pd(2), three equivalent Pd(3), and six equivalent Pd(1) atoms to form CePd12 cuboctahedra that share corners with twelve equivalent Ce(1)Pd12 cuboctahedra, edges with six equivalent Pd(2)Ce4Pd8 cuboctahedra, faces with three equivalent Pd(2)Ce4Pd8 cuboctahedra, faces with six equivalent Ce(1)Pd12 cuboctahedra, and  a faceface with one Sn(1)Pd6 octahedra. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to four equivalent Ce(1) and two equivalent Pd(2) atoms. In the second Pd site, Pd(2) is bonded to four equivalent Ce(1), four equivalent Pd(1), and four equivalent Pd(2) atoms to form distorted PdCe4Pd8 cuboctahedra that share edges with eight equivalent Ce(1)Pd12 cuboctahedra, faces with four equivalent Ce(1)Pd12 cuboctahedra, and faces with six equivalent Pd(2)Ce4Pd8 cuboctahedra. In the third Pd site, Pd(3) is bonded in a 5-coordinate geometry to four equivalent Ce(1) and one Sn(1) atom. Sn(1) is bonded to six equivalent Pd(3) atoms to form SnPd6 octahedra that share faces with eight equivalent Ce(1)Pd12 cuboctahedra. is represented by the CIF file [CIF]
