Materials Data on U(FeP3)4 by Materials Project
UFe4P12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. U3+ is bonded to twelve equivalent P1- atoms to form UP12 cuboctahedra that share faces with eight equivalent FeP6 octahedra. All U–P bond lengths are 2.96 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 UP12 cuboctahedra. The corner-sharing octahedral tilt angles are 58°. All Fe–P bond lengths are 2.23 Å. P1- is bonded in a distorted bent 120 degrees geometry to one U3+, two equivalent Fe+2.25+, and two equivalent P1- atoms. Both P–P bond lengths are 2.35 Å.
