Tb7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. In the second Tb site, Tb(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. In the third Tb site, Tb(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 Tb(1), two equivalent Tb(3), and three equivalent Tb(2) atoms.
Tb7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. All Tb(1)-Rh(1) bond lengths are 2.80 Å. In the second Tb site, Tb(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. Both Tb(3)-Rh(1) bond lengths are 2.81 Å. In the third Tb site, Tb(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. There are two shorter (2.86 Å) and one longer (2.88 Å) Tb(2)-Rh(1) bond length. Rh(1) is bonded in a 6-coordinate geometry to one Tb(1), two equivalent Tb(3), and three equivalent Tb(2) atoms.
