Materials Data on PrSb2 by Materials Project
PrSb2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Pr3+ is bonded in a 9-coordinate geometry to nine Sb+1.50- atoms. There are a spread of Pr–Sb bond distances ranging from 3.21–3.50 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 Pr3+ and one Sb+1.50- atom. The Sb–Sb bond length is 2.85 Å. In the second Sb+1.50- site, Sb+1.50- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Sb+1.50- atoms. There are two shorter (3.11 Å) and two longer (3.18 Å) Sb–Sb bond lengths.
