The material structure described by Sm(RhSn2)2 crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 6-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 7-coordinate geometry to one Sn(1), three equivalent Sn(3), and three equivalent Sn(4) atoms. In the second Rh site, Rh(2) is bonded in a 7-coordinate geometry to one Sn(4), three equivalent Sn(1), and three equivalent Sn(2) atoms. There are four inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to two equivalent Sm(1), one Rh(1), and three equivalent Rh(2) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to two equivalent Sm(1) and three equivalent Rh(2) atoms. In the third Sn site, Sn(3) is bonded in a 5-coordinate geometry to two equivalent Sm(1) and three equivalent Rh(1) atoms. In the fourth Sn site, Sn(4) is bonded to one Rh(2) and three equivalent Rh(1) atoms to form a mixture of distorted corner and edge-sharing SnRh4 tetrahedra. is represented by the CIF file [CIF]
