Tb5Rh6Sn18 crystallizes in the cubic F-43m space group. The structure consists of four 7440-31-5 atoms inside a Tb5Rh6Sn17 framework. In the Tb5Rh6Sn17 framework, there are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 13-coordinate geometry to three equivalent Rh(1), one Sn(4), three equivalent Sn(1), and six equivalent Sn(3) atoms. In the second Tb site, Tb(2) is bonded in a 18-coordinate geometry to six equivalent Rh(1) and twelve equivalent Sn(3) atoms. Rh(1) is bonded in a 8-coordinate geometry to one Tb(2), two equivalent Tb(1), two equivalent Sn(1), and four equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(4) is bonded in a tetrahedral geometry to four equivalent Tb(1) atoms. In the second Sn site, Sn(1) is bonded in a hexagonal planar geometry to three equivalent Tb(1) and three equivalent Rh(1) atoms. In the third Sn site, Sn(3) is bonded in a 2-coordinate geometry to one Tb(2), two equivalent Tb(1), and two equivalent Rh(1) atoms.
