The material structure described by Tb4Rh7Sb6 crystallizes in the cubic Im-3m space group. Tb(1) is bonded to six equivalent Rh(2) and six equivalent Sb(1) atoms to form TbSb6Rh6 cuboctahedra that share corners with twelve equivalent Tb(1)Sb6Rh6 cuboctahedra, faces with six equivalent Tb(1)Sb6Rh6 cuboctahedra, and faces with two equivalent Rh(1)Sb6 octahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to six equivalent Sb(1) atoms to form RhSb6 octahedra that share faces with eight equivalent Tb(1)Sb6Rh6 cuboctahedra. In the second Rh site, Rh(2) is bonded in a 8-coordinate geometry to four equivalent Tb(1) and four equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Tb(1), one Rh(1), and four equivalent Rh(2) atoms. is represented by the CIF file [CIF]
