Materials Data on HfSb3 by Materials Project
HfSb3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Hf4+ is bonded to twelve equivalent Sb+1.33- atoms to form a mixture of face and corner-sharing HfSb12 cuboctahedra. There are six shorter (3.25 Å) and six longer (3.27 Å) Hf–Sb bond lengths. Sb+1.33- is bonded in a 4-coordinate geometry to four equivalent Hf4+ atoms.
