Materials Data on SmCdNi4 by Materials Project
SmNi4Cd is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Sm is bonded in a 12-coordinate geometry to twelve equivalent Ni and four equivalent Cd atoms. All Sm–Ni bond lengths are 2.94 Å. All Sm–Cd bond lengths are 3.07 Å. Ni is bonded to three equivalent Sm, six equivalent Ni, and three equivalent Cd atoms to form a mixture of edge, corner, and face-sharing NiSm3Cd3Ni6 cuboctahedra. There are three shorter (2.48 Å) and three longer (2.53 Å) Ni–Ni bond lengths. All Ni–Cd bond lengths are 2.94 Å. Cd is bonded in a 4-coordinate geometry to four equivalent Sm and twelve equivalent Ni atoms.
