The structure described by HfSb2 crystallizes in the tetragonal P4/nmm space group. Hf(1) is bonded in a 9-coordinate geometry to four equivalent Sb(2) and five equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to five equivalent Hf(1) atoms to form a mixture of distorted corner and edge-sharing SbHf5 trigonal bipyramids. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Sb(2) atoms. is represented by the CIF file [CIF]
