Hf10(InSb)3 crystallizes in the hexagonal P-62m 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 In(1) and three equivalent Sb(1) atoms. In the second Hf site, Hf(2) is bonded in a 5-coordinate geometry to three equivalent In(1) and two equivalent Sb(1) atoms. In the third Hf site, Hf(3) is bonded in a 5-coordinate geometry to two equivalent In(1) and three equivalent Sb(1) atoms. In(1) is bonded in a 9-coordinate geometry to two equivalent Hf(3), three equivalent Hf(2), and four equivalent Hf(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to two equivalent Hf(2), three equivalent Hf(3), and four equivalent Hf(1) atoms.
Hf10(InSb)3 crystallizes in the hexagonal P-62m 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 In(1) and three equivalent Sb(1) atoms. All Hf(1)-In(1) bond lengths are 2.99 Å. All Hf(1)-Sb(1) bond lengths are 2.99 Å. In the second Hf site, Hf(2) is bonded in a 5-coordinate geometry to three equivalent In(1) and two equivalent Sb(1) atoms. There are two shorter (2.90 Å) and one longer (3.07 Å) Hf(2)-In(1) bond length. Both Hf(2)-Sb(1) bond lengths are 3.12 Å. In the third Hf site, Hf(3) is bonded in a 5-coordinate geometry to two equivalent In(1) and three equivalent Sb(1) atoms. Both Hf(3)-In(1) bond lengths are 3.12 Å. There are two shorter (2.90 Å) and one longer (3.06 Å) Hf(3)-Sb(1) bond length. In(1) is bonded in a 9-coordinate geometry to two equivalent Hf(3), three equivalent Hf(2), and four equivalent Hf(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to two equivalent Hf(2), three equivalent Hf(3), and four equivalent Hf(1) atoms.
