The material described by Sm3Rh2 crystallizes in the trigonal R-3 space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 5-coordinate geometry to five equivalent Rh(1) atoms. In the second Sm site, Sm(3) is bonded in an octahedral geometry to six equivalent Rh(1) atoms. In the third Sm site, Sm(2) is bonded in a 6-coordinate geometry to six equivalent Rh(1) atoms. Rh(1) is bonded in a 8-coordinate geometry to one Sm(3), two equivalent Sm(2), and five equivalent Sm(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
