The crystal structure described by Hf6NiBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 4-coordinate geometry to two equivalent Ni(1) and two equivalent Bi(1) atoms. In the second Hf site, Hf(2) is bonded in a 5-coordinate geometry to one Ni(1) and four equivalent Bi(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Hf(2) and six equivalent Hf(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Hf(2) atoms. is represented by the CIF card [CIF]
