Materials Data on SmIn2Rh by Materials Project

SmRhIn2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sm is bonded in a 1-coordinate geometry to three equivalent Rh and ten equivalent In atoms. There are one shorter (2.89 Å) and two longer (3.15 Å) Sm–Rh bond lengths. There are a spread of Sm–In bond distances ranging from 3.35–3.49 Å. Rh is bonded in a 9-coordinate geometry to three equivalent Sm and six equivalent In atoms. There are two shorter (2.80 Å) and four longer (2.83 Å) Rh–In bond lengths. In is bonded in a 3-coordinate geometry to five equivalent Sm and three equivalent Rh atoms.

Materials Data on SmIn5Rh by Materials Project

SmRhIn5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Sm is bonded to twelve In atoms to form SmIn12 cuboctahedra that share corners with four equivalent SmIn12 cuboctahedra, faces with four equivalent SmIn12 cuboctahedra, and faces with four equivalent InSm4In8 cuboctahedra. There are eight shorter (3.28 Å) and four longer (3.32 Å) Sm–In bond lengths. Rh is bonded in a body-centered cubic geometry to eight equivalent In atoms. All Rh–In bond lengths are 2.78 Å. There are two inequivalent In sites. In the first In site, In is bonded in a 4-coordinate geometry to two equivalent Sm, two equivalent Rh, and two equivalent In atoms. Both In–In bond lengths are 3.28 Å. In the second In site, In is bonded to four equivalent Sm and eight equivalent In atoms to form distorted InSm4In8 cuboctahedra that share corners with four equivalent InSm4In8 cuboctahedra, faces with four equivalent SmIn12 cuboctahedra, and faces with four equivalent InSm4In8 cuboctahedra.
