Materials Data on Tb(FeP3)4 by Materials Project
Abstract
TbFe4P12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Tb3+ is bonded to twelve equivalent P1- atoms to form TbP12 cuboctahedra that share faces with eight equivalent FeP6 octahedra. All Tb–P bond lengths are 2.98 Å. Fe+2.25+ is bonded to six equivalent P1- atoms to form FeP6 octahedra that share corners with six equivalent FeP6 octahedra and faces with two equivalent TbP12 cuboctahedra. The corner-sharing octahedral tilt angles are 59°. All Fe–P bond lengths are 2.24 Å. P1- is bonded in a 2-coordinate geometry to one Tb3+, two equivalent Fe+2.25+, and two equivalent P1- atoms. There are one shorter (2.30 Å) and one longer (2.35 Å) P–P bond lengths.
