Abstract

PrFeSb3 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded in a 9-coordinate geometry to nine Sb2- atoms. There are a spread of Pr–Sb bond distances ranging from 3.23–3.44 Å. In the second Pr3+ site, Pr3+ is bonded in a 9-coordinate geometry to nine Sb2- atoms. There are a spread of Pr–Sb bond distances ranging from 3.24–3.38 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six Sb2- atoms to form a mixture of distorted edge and corner-sharing FeSb6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of Fe–Sb bond distances ranging from 2.57–2.67 Å. In the second Fe3+ site, Fe3+ is bonded to six Sb2- atoms to form a mixture of face, edge, and corner-sharing FeSb6 octahedra. The corner-sharing octahedra tilt angles range from 42–45°. There are a spread of Fe–Sb bond distances ranging from 2.59–2.73 Å. There are six inequivalent Sb2- sites. In the first Sb2- site, Sb2- is bonded in a 6-coordinate geometry to one Pr3+, four equivalent Fe3+, and one Sb2- atom. The Sb–Sb bond length is 3.10 Å.more »« less
