CeFe4P12 crystallizes in the cubic Im-3 space group. Ce(1) is bonded to twelve equivalent P(1) atoms to form CeP12 cuboctahedra that share faces with eight equivalent Fe(1)P6 octahedra. Fe(1) is bonded to six equivalent P(1) atoms to form FeP6 octahedra that share corners with six equivalent Fe(1)P6 octahedra and faces with two equivalent Ce(1)P12 cuboctahedra. The corner-sharing octahedral tilt angles are 59°. P(1) is bonded in a 5-coordinate geometry to one Ce(1), two equivalent Fe(1), and two equivalent P(1) atoms.
CeFe4P12 crystallizes in the cubic Im-3 space group. Ce(1) is bonded to twelve equivalent P(1) atoms to form CeP12 cuboctahedra that share faces with eight equivalent Fe(1)P6 octahedra. All Ce(1)-P(1) bond lengths are 2.97 Å. Fe(1) is bonded to six equivalent P(1) atoms to form FeP6 octahedra that share corners with six equivalent Fe(1)P6 octahedra and faces with two equivalent Ce(1)P12 cuboctahedra. The corner-sharing octahedral tilt angles are 59°. All Fe(1)-P(1) bond lengths are 2.23 Å. P(1) is bonded in a 5-coordinate geometry to one Ce(1), two equivalent Fe(1), and two equivalent P(1) atoms. There is one shorter (2.30 Å) and one longer (2.34 Å) P(1)-P(1) bond length.
