Abstract

GdSm4S5 is Caswellsilverite-like structured and crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Gd is bonded to six S atoms to form GdS6 octahedra that share corners with two equivalent GdS6 octahedra, corners with four equivalent SmS6 octahedra, edges with two equivalent GdS6 octahedra, and edges with ten SmS6 octahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are two shorter (2.87 Å) and four longer (2.88 Å) Gd–S bond lengths. There are two inequivalent Sm sites. In the first Sm site, Sm is bonded to six S atoms to form SmS6 octahedra that share corners with six SmS6 octahedra, edges with four equivalent GdS6 octahedra, and edges with eight SmS6 octahedra. The corner-sharing octahedra tilt angles range from 0–3°. There are a spread of Sm–S bond distances ranging from 2.87–2.93 Å. In the second Sm site, Sm is bonded to six S atoms to form SmS6 octahedra that share corners with two equivalent GdS6 octahedra, corners with four SmS6 octahedra, an edgeedge with one GdS6 octahedra, and edges with eleven SmS6 octahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are a spread of Sm–S bond distances ranging from 2.87–2.96 Å. There are threemore »« less
