The structure described by Tb7RhBr12 is trigonal omega-derived structured and crystallizes in the trigonal R-3 space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to one Rh(1), two equivalent Br(2), and three equivalent Br(1) atoms to form TbRhBr5 octahedra that share corners with three equivalent Tb(1)RhBr5 octahedra,  an edgeedge with one Tb(2)Br6 octahedra, and edges with five equivalent Tb(1)RhBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second Tb site, Tb(2) is bonded to six equivalent Br(2) atoms to form edge-sharing TbBr6 octahedra. Rh(1) is bonded in an octahedral geometry to six equivalent Tb(1) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a T-shaped geometry to three equivalent Tb(1) atoms. In the second Br site, Br(2) is bonded in a distorted T-shaped geometry to one Tb(2) and two equivalent Tb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
