Materials Data on Yb(FeP3)4 by Materials Project
YbFe4P12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Yb2+ is bonded to twelve equivalent P1- atoms to form YbP12 cuboctahedra that share faces with eight equivalent FeP6 octahedra. All Yb–P bond lengths are 2.99 Å. Fe+2.50+ is bonded to six equivalent P1- atoms to form FeP6 octahedra that share corners with six equivalent FeP6 octahedra and faces with two equivalent YbP12 cuboctahedra. The corner-sharing octahedral tilt angles are 60°. All Fe–P bond lengths are 2.24 Å. P1- is bonded in a 2-coordinate geometry to one Yb2+, two equivalent Fe+2.50+, and two equivalent P1- atoms. There are one shorter (2.28 Å) and one longer (2.34 Å) P–P bond lengths.
