Ho4Sb3 crystallizes in the cubic I-43d space group. Ho(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Sb(1) is bonded to eight equivalent Ho(1) atoms to form a mixture of distorted corner, face, and edge-sharing SbHo8 hexagonal bipyramids.
Ho4Sb3 crystallizes in the cubic I-43d space group. Ho(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. There are three shorter (3.05 Å) and three longer (3.27 Å) Ho(1)-Sb(1) bond lengths. Sb(1) is bonded to eight equivalent Ho(1) atoms to form a mixture of distorted corner, face, and edge-sharing SbHo8 hexagonal bipyramids.
