Materials Data on Sm5Sb3H by Materials Project
Sm5Sb3H crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Sm2+ sites. In the first Sm2+ site, Sm2+ is bonded to five equivalent Sb3- and two equivalent H1- atoms to form a mixture of distorted face, edge, and corner-sharing SmSb5H2 pentagonal bipyramids. There are a spread of Sm–Sb bond distances ranging from 3.13–3.40 Å. Both Sm–H bond lengths are 2.82 Å. In the second Sm2+ site, Sm2+ is bonded in a 6-coordinate geometry to two equivalent Sm2+ and six equivalent Sb3- atoms. Both Sm–Sm bond lengths are 3.17 Å. All Sm–Sb bond lengths are 3.27 Å. Sb3- is bonded in a 9-coordinate geometry to nine Sm2+ atoms. H1- is bonded to six equivalent Sm2+ atoms to form face-sharing HSm6 octahedra.
