ScCu4Sn crystallizes in the cubic F-43m space group. Sc(1) is bonded in a 16-coordinate geometry to twelve equivalent Cu(1) and four equivalent Sn(1) atoms. Cu(1) is bonded to three equivalent Sc(1), six equivalent Cu(1), and three equivalent Sn(1) atoms to form a mixture of edge, face, and corner-sharing CuSc3Cu6Sn3 cuboctahedra. Sn(1) is bonded in a 16-coordinate geometry to four equivalent Sc(1) and twelve equivalent Cu(1) atoms.
ScCu4Sn crystallizes in the cubic F-43m space group. Sc(1) is bonded in a 16-coordinate geometry to twelve equivalent Cu(1) and four equivalent Sn(1) atoms. All Sc(1)-Cu(1) bond lengths are 2.94 Å. All Sc(1)-Sn(1) bond lengths are 3.08 Å. Cu(1) is bonded to three equivalent Sc(1), six equivalent Cu(1), and three equivalent Sn(1) atoms to form a mixture of edge, face, and corner-sharing CuSc3Cu6Sn3 cuboctahedra. There are three shorter (2.50 Å) and three longer (2.52 Å) Cu(1)-Cu(1) bond lengths. All Cu(1)-Sn(1) bond lengths are 2.95 Å.
