The structure described by SmCu4Pd crystallizes in the trigonal R3m space group. Sm(1) is bonded in a 16-coordinate geometry to three equivalent Pd(1), four equivalent Cu(2), and nine equivalent Cu(1) atoms. Pd(1) is bonded to three equivalent Sm(1), three equivalent Cu(2), and six equivalent Cu(1) atoms to form a mixture of corner and edge-sharing PdSm3Cu9 cuboctahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 11-coordinate geometry to three equivalent Sm(1), two equivalent Pd(1), two equivalent Cu(2), and four equivalent Cu(1) atoms. In the second Cu site, Cu(2) is bonded in a 13-coordinate geometry to four equivalent Sm(1), three equivalent Pd(1), and six equivalent Cu(1) atoms. is represented by the CIF card [CIF]
