The crystal structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
