Abstract

Sm10Sb3Se7 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Sm+2.30+ sites. In the first Sm+2.30+ site, Sm+2.30+ is bonded to one Sb3- and five Se2- atoms to form a mixture of corner and edge-sharing SmSbSe5 octahedra. The corner-sharing octahedra tilt angles range from 0–3°. The Sm–Sb bond length is 3.09 Å. There are a spread of Sm–Se bond distances ranging from 2.95–3.02 Å. In the second Sm+2.30+ site, Sm+2.30+ is bonded to two Sb3- and four Se2- atoms to form SmSb2Se4 octahedra that share corners with six SmSb2Se4 octahedra and edges with twelve SmSbSe5 octahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are one shorter (3.03 Å) and one longer (3.04 Å) Sm–Sb bond lengths. There are a spread of Sm–Se bond distances ranging from 3.01–3.03 Å. In the third Sm+2.30+ site, Sm+2.30+ is bonded to two equivalent Sb3- and four Se2- atoms to form a mixture of corner and edge-sharing SmSb2Se4 octahedra. The corner-sharing octahedra tilt angles range from 2–4°. There are one shorter (3.07 Å) and one longer (3.08 Å) Sm–Sb bond lengths. There are a spread of Sm–Se bond distances ranging from 2.96–3.03 Å.more »« less
