Materials Data on Pr(FeSb3)4 by Materials Project
PrFe4Sb12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Pr3+ is bonded to twelve equivalent Sb+1.25- atoms to form PrSb12 cuboctahedra that share faces with eight equivalent FeSb6 octahedra. All Pr–Sb bond lengths are 3.42 Å. Fe3+ is bonded to six equivalent Sb+1.25- atoms to form FeSb6 octahedra that share corners with six equivalent FeSb6 octahedra and faces with two equivalent PrSb12 cuboctahedra. The corner-sharing octahedral tilt angles are 52°. All Fe–Sb bond lengths are 2.56 Å. Sb+1.25- is bonded in a 2-coordinate geometry to one Pr3+, two equivalent Fe3+, and two equivalent Sb+1.25- atoms. There are one shorter (2.99 Å) and one longer (3.04 Å) Sb–Sb bond lengths.
