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.
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. All Sm(1)-Ag(1) bond lengths are 3.09 Å. All Sm(1)-Cu(1) bond lengths are 2.96 Å. Ag(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1) and twelve equivalent Cu(1) atoms. All Ag(1)-Cu(1) bond lengths are 2.96 Å. 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. There are three shorter (2.49 Å) and three longer (2.55 Å) Cu(1)-Cu(1) bond lengths.
