HfNi2Sb crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) and six equivalent Sb(1) atoms. Ni(1) is bonded in a 8-coordinate geometry to three equivalent Hf(1), one Ni(1), and four equivalent Sb(1) atoms. Sb(1) is bonded in a 14-coordinate geometry to six equivalent Hf(1) and eight equivalent Ni(1) atoms.
HfNi2Sb crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) and six equivalent Sb(1) atoms. All Hf(1)-Ni(1) bond lengths are 2.65 Å. All Hf(1)-Sb(1) bond lengths are 3.18 Å. Ni(1) is bonded in a 8-coordinate geometry to three equivalent Hf(1), one Ni(1), and four equivalent Sb(1) atoms. The Ni(1)-Ni(1) bond length is 2.37 Å. There is one shorter (2.59 Å) and three longer (2.82 Å) Ni(1)-Sb(1) bond lengths. Sb(1) is bonded in a 14-coordinate geometry to six equivalent Hf(1) and eight equivalent Ni(1) atoms.
