Abstract

Sr(TbS2)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Sr–S bond distances ranging from 3.10–3.32 Å. There are two inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing TbS6 octahedra. The corner-sharing octahedra tilt angles range from 48–64°. There are a spread of Tb–S bond distances ranging from 2.73–2.79 Å. In the second Tb3+ site, Tb3+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing TbS6 octahedra. The corner-sharing octahedra tilt angles range from 48–64°. There are a spread of Tb–S bond distances ranging from 2.70–2.80 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Sr2+ and three Tb3+ atoms. In the second S2- site, S2- is bonded to two equivalent Sr2+ and three equivalent Tb3+ atoms to form distorted edge-sharing SSr2Tb3 square pyramids. In the third S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Sr2+ and three Tb3+ atoms. In the fourth S2- site,more »« less
