Materials Data on SmSb by Materials Project

SmSb is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Sm3+ is bonded to six equivalent Sb3- atoms to form a mixture of edge and corner-sharing SmSb6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sm–Sb bond lengths are 3.16 Å. Sb3- is bonded to six equivalent Sm3+ atoms to form a mixture of edge and corner-sharing SbSm6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on SmSb2 by Materials Project

SmSb2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Sm3+ is bonded in a 9-coordinate geometry to nine Sb+1.50- atoms. There are a spread of Sm–Sb bond distances ranging from 3.19–3.45 Å. There are two inequivalent Sb+1.50- sites. In the first Sb+1.50- site, Sb+1.50- is bonded in a 6-coordinate geometry to five equivalent Sm3+ and one Sb+1.50- atom. The Sb–Sb bond length is 2.86 Å. In the second Sb+1.50- site, Sb+1.50- is bonded in a 8-coordinate geometry to four equivalent Sm3+ and four equivalent Sb+1.50- atoms. All Sb–Sb bond lengths are 3.11 Å.

Materials Data on Sm4Sb3 by Materials Project

Sm4Sb3 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Sm+2.25+ is bonded to six equivalent Sb3- atoms to form a mixture of distorted edge, corner, and face-sharing SmSb6 octahedra. The corner-sharing octahedra tilt angles range from 18–49°. There are three shorter (3.14 Å) and three longer (3.38 Å) Sm–Sb bond lengths. Sb3- is bonded to eight equivalent Sm+2.25+ atoms to form a mixture of distorted edge, corner, and face-sharing SbSm8 hexagonal bipyramids.
