Materials Data on SmSb2 by Materials Project
SmSb2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Sm3+ is bonded in a 9-coordinate geometry to nine Sb+1.50- atoms. There are a spread of Sm–Sb bond distances ranging from 3.19–3.45 Å. There are two inequivalent Sb+1.50- sites. In the first Sb+1.50- site, Sb+1.50- is bonded in a 6-coordinate geometry to five equivalent Sm3+ and one Sb+1.50- atom. The Sb–Sb bond length is 2.86 Å. In the second Sb+1.50- site, Sb+1.50- is bonded in a 8-coordinate geometry to four equivalent Sm3+ and four equivalent Sb+1.50- atoms. All Sb–Sb bond lengths are 3.11 Å.
