The material described by Hf2Rh crystallizes in the cubic Fd-3m space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 6-coordinate geometry to six equivalent Rh(1) atoms. In the second Hf site, Hf(2) is bonded in a 2-coordinate geometry to four equivalent Rh(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Hf(2) atoms. is represented by the CIF file [CIF]
