Hf2Co 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 Co(1) atoms. In the second Hf site, Hf(2) is bonded in a 2-coordinate geometry to four equivalent Co(1) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Hf(2) atoms.
Hf2Co 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 Co(1) atoms. All Hf(1)-Co(1) bond lengths are 2.70 Å. In the second Hf site, Hf(2) is bonded in a 2-coordinate geometry to four equivalent Co(1) atoms. There are two shorter (2.61 Å) and two longer (3.05 Å) Hf(2)-Co(1) bond lengths. Co(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Hf(2) atoms.
