The structure described by Tb5(Rh2Ge5)2 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 16-coordinate geometry to four equivalent Rh(1), four equivalent Ge(2), and eight equivalent Ge(3) atoms. In the second Tb site, Tb(2) is bonded to four equivalent Rh(1), two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms to form face-sharing TbGe8Rh4 cuboctahedra. In the third Tb site, Tb(3) is bonded in a 14-coordinate geometry to four equivalent Rh(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. Rh(1) is bonded in a 10-coordinate geometry to one Tb(1), two equivalent Tb(2), two equivalent Tb(3), one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Tb(2), four equivalent Tb(3), two equivalent Rh(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Tb(1), two equivalent Tb(2), two equivalent Tb(3), two equivalent Rh(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 2-coordinate geometry to one Tb(2), one Tb(3), two equivalent Tb(1), and two equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
