The material structure described by Sm5Rh4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 6-coordinate geometry to one Rh(3), two equivalent Rh(2), and three equivalent Rh(1) atoms. In the second Sm site, Sm(2) is bonded in a 7-coordinate geometry to one Rh(2), two equivalent Rh(3), and four equivalent Rh(1) atoms. In the third Sm site, Sm(3) is bonded to two equivalent Rh(1), two equivalent Rh(2), and two equivalent Rh(3) atoms to form distorted corner-sharing SmRh6 octahedra. The corner-sharing octahedral tilt angles range from 50-55°. There are three inequivalent Rh sites. In the first Rh site, Rh(3) is bonded in a 9-coordinate geometry to two equivalent Sm(1), two equivalent Sm(3), four equivalent Sm(2), and one Rh(2) atom. In the second Rh site, Rh(1) is bonded in a 8-coordinate geometry to one Sm(3), three equivalent Sm(1), and four equivalent Sm(2) atoms. In the third Rh site, Rh(2) is bonded in a 9-coordinate geometry to two equivalent Sm(2), two equivalent Sm(3), four equivalent Sm(1), and one Rh(3) atom. is represented by the CIF file [CIF]
