TbRhIn5 crystallizes in the tetragonal P4/mmm space group. Tb(1) is bonded to four equivalent In(1) and eight equivalent In(2) atoms to form TbIn12 cuboctahedra that share corners with four equivalent Tb(1)In12 cuboctahedra, faces with four equivalent Tb(1)In12 cuboctahedra, and faces with four equivalent In(1)Tb4In8 cuboctahedra. Rh(1) is bonded in a body-centered cubic geometry to eight equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Tb(1) and eight equivalent In(2) atoms to form distorted InTb4In8 cuboctahedra that share corners with four equivalent In(1)Tb4In8 cuboctahedra, faces with four equivalent Tb(1)In12 cuboctahedra, and faces with four equivalent In(1)Tb4In8 cuboctahedra. In the second In site, In(2) is bonded in a 4-coordinate geometry to two equivalent Tb(1), two equivalent Rh(1), and two equivalent In(1) atoms.
