SmNi4Cd is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Sm(1) is bonded in a 16-coordinate geometry to twelve equivalent Ni(1) and four equivalent Cd(1) atoms. Ni(1) is bonded to three equivalent Sm(1), six equivalent Ni(1), and three equivalent Cd(1) atoms to form a mixture of face, corner, and edge-sharing NiSm3Cd3Ni6 cuboctahedra. Cd(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1) and twelve equivalent Ni(1) atoms.
SmNi4Cd is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Sm(1) is bonded in a 16-coordinate geometry to twelve equivalent Ni(1) and four equivalent Cd(1) atoms. All Sm(1)-Ni(1) bond lengths are 2.92 Å. All Sm(1)-Cd(1) bond lengths are 3.04 Å. Ni(1) is bonded to three equivalent Sm(1), six equivalent Ni(1), and three equivalent Cd(1) atoms to form a mixture of face, corner, and edge-sharing NiSm3Cd3Ni6 cuboctahedra. There are three shorter (2.46 Å) and three longer (2.51 Å) Ni(1)-Ni(1) bond lengths. All Ni(1)-Cd(1) bond lengths are 2.91 Å.
