In the second Hf site, Hf(2) is bonded in a 2-coordinate geometry to two equivalent Rh(1), two equivalent In(2), and four equivalent In(1) atoms. In the third Hf site, Hf(3) is bonded in a 8-coordinate geometry to four equivalent In(1) and four equivalent In(2) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Hf(2), four equivalent Hf(1), one In(1), and two equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 12-coordinate geometry to two equivalent Hf(1), two equivalent Hf(3), four equivalent Hf(2), one Rh(1), one In(2), and two equivalent In(1) atoms. In the second In site, In(2) is bonded in a 13-coordinate geometry to two equivalent Hf(2), two equivalent Hf(3), four equivalent Hf(1), two equivalent Rh(1), one In(1), and two equivalent In(2) atoms.
