Materials Data on SmBS3 by Materials Project
SmBS3 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Sm3+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Sm–S bond distances ranging from 2.87–3.41 Å. B3+ is bonded in a trigonal planar geometry to three S2- atoms. There are a spread of B–S bond distances ranging from 1.80–1.83 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 1-coordinate geometry to three equivalent Sm3+ and one B3+ atom. In the second S2- site, S2- is bonded in a 1-coordinate geometry to three equivalent Sm3+ and one B3+ atom. In the third S2- site, S2- is bonded in a distorted single-bond geometry to three equivalent Sm3+ and one B3+ atom.
