The material described by Hf2Bi crystallizes in the monoclinic C2/m space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 3-coordinate geometry to three equivalent Bi(1) atoms. In the second Hf site, Hf(2) is bonded in a 5-coordinate geometry to five equivalent Bi(1) atoms. Bi(1) is bonded in a 8-coordinate geometry to three equivalent Hf(1) and five equivalent Hf(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
