The crystal structure described by Hf4RhNi crystallizes in the cubic F-43m space group. There are three inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 6-coordinate geometry to three equivalent Rh(1) and three equivalent Ni(1) atoms. In the second Hf site, Hf(2) is bonded in a 2-coordinate geometry to two equivalent Rh(1) atoms. In the third Hf site, Hf(3) is bonded in a 4-coordinate geometry to two equivalent Rh(1) and two equivalent Ni(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), and three equivalent Hf(3) atoms. Ni(1) is bonded in a 6-coordinate geometry to three equivalent Hf(1) and three equivalent Hf(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
