La4Sb3 crystallizes in the cubic I-43d space group. La(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Sb(1) is bonded to eight equivalent La(1) atoms to form a mixture of distorted corner, edge, and face-sharing SbLa8 hexagonal bipyramids.
La4Sb3 crystallizes in the cubic I-43d space group. La(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. There are three shorter (3.23 Å) and three longer (3.51 Å) La(1)-Sb(1) bond lengths. Sb(1) is bonded to eight equivalent La(1) atoms to form a mixture of distorted corner, edge, and face-sharing SbLa8 hexagonal bipyramids.
