Materials Data on Pr(FeSb3)5 by Materials Project
Abstract
Pr(FeSb3)5 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded to twelve Sb+1.20- atoms to form PrSb12 cuboctahedra that share faces with eight FeSb6 octahedra. There are six shorter (3.41 Å) and six longer (3.42 Å) Pr–Sb bond lengths. In the second Pr3+ site, Pr3+ is bonded to twelve Sb+1.20- atoms to form PrSb12 cuboctahedra that share faces with eight FeSb6 octahedra. There are three shorter (3.40 Å) and nine longer (3.41 Å) Pr–Sb bond lengths. There are six inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six Sb+1.20- atoms to form FeSb6 octahedra that share corners with six FeSb6 octahedra and a faceface with one PrSb12 cuboctahedra. The corner-sharing octahedra tilt angles range from 51–52°. There are three shorter (2.52 Å) and three longer (2.56 Å) Fe–Sb bond lengths. In the second Fe3+ site, Fe3+ is bonded to six Sb+1.20- atoms to form FeSb6 octahedra that share corners with six FeSb6 octahedra and faces with two equivalent PrSb12 cuboctahedra. The corner-sharing octahedral tilt angles are 52°. There are four shorter (2.54 Å) and two longer (2.55 Å) Fe–Sb bondmore »
