The material described by SmAgCu4 crystallizes in the cubic F-43m space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1) and twelve equivalent Cu(1) atoms. Ag(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1) and twelve equivalent Cu(1) atoms. Cu(1) is bonded to three equivalent Sm(1), three equivalent Ag(1), and six equivalent Cu(1) atoms to form a mixture of edge, face, and corner-sharing CuSm3Cu6Ag3 cuboctahedra. is represented by the CIF file [CIF]
