The structure described by Sm3Rh2Si2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 9-coordinate geometry to four equivalent Rh(1), two equivalent Si(2), and three equivalent Si(1) atoms. In the second Sm site, Sm(2) is bonded in a 9-coordinate geometry to four equivalent Rh(1), two equivalent Si(1), and three equivalent Si(2) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), one Si(1), and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1), four equivalent Sm(2), and two equivalent Rh(1) atoms. In the second Si site, Si(2) is bonded in a 4-coordinate geometry to two equivalent Sm(1), six equivalent Sm(2), and four equivalent Rh(1) atoms. is represented by the CIF file [CIF]
