The material described by Sm5(Rh2Sn5)2 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 16-coordinate geometry to four equivalent Rh(1), four equivalent Sn(2), and eight equivalent Sn(3) atoms. In the second Sm site, Sm(2) is bonded to four equivalent Rh(1), two equivalent Sn(1), two equivalent Sn(3), and four equivalent Sn(2) atoms to form face-sharing SmSn8Rh4 cuboctahedra. In the third Sm site, Sm(3) is bonded in a 14-coordinate geometry to four equivalent Rh(1), two equivalent Sn(3), four equivalent Sn(1), and four equivalent Sn(2) atoms. Rh(1) is bonded in a 10-coordinate geometry to one Sm(1), two equivalent Sm(2), two equivalent Sm(3), one Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Sm(2), four equivalent Sm(3), two equivalent Rh(1), and one Sn(1) atom. In the second Sn site, Sn(2) is bonded in a 2-coordinate geometry to one Sm(1), two equivalent Sm(2), two equivalent Sm(3), and two equivalent Rh(1) atoms. In the third Sn site, Sn(3) is bonded in a 2-coordinate geometry to one Sm(2), one Sm(3), two equivalent Sm(1), and two equivalent Rh(1) atoms. is represented by the CIF card [CIF]
