Ho7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. In the second Ho site, Ho(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. In the third Ho site, Ho(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to one Ho(1), two equivalent Ho(3), and three equivalent Ho(2) atoms.
Ho7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms.
