Materials Data on Sm2Sb5 by Materials Project
Abstract
Sm2Sb5 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are four inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 9-coordinate geometry to nine Sb+1.20- atoms. There are a spread of Sm–Sb bond distances ranging from 3.23–3.34 Å. In the second Sm3+ site, Sm3+ is bonded in a 9-coordinate geometry to nine Sb+1.20- atoms. There are a spread of Sm–Sb bond distances ranging from 3.16–3.39 Å. In the third Sm3+ site, Sm3+ is bonded in a 9-coordinate geometry to nine Sb+1.20- atoms. There are a spread of Sm–Sb bond distances ranging from 3.24–3.43 Å. In the fourth Sm3+ site, Sm3+ is bonded in a 9-coordinate geometry to nine Sb+1.20- atoms. There are a spread of Sm–Sb bond distances ranging from 3.18–3.38 Å. There are ten inequivalent Sb+1.20- sites. In the first Sb+1.20- site, Sb+1.20- is bonded in a 8-coordinate geometry to four Sm3+ and four Sb+1.20- atoms. There are two shorter (2.97 Å) and two longer (3.12 Å) Sb–Sb bond lengths. In the second Sb+1.20- site, Sb+1.20- is bonded in a 5-coordinate geometry to three Sm3+ and two equivalent Sb+1.20- atoms. Both Sb–Sb bond lengths are 2.94 Å. In the third Sb+1.20-more »
