The material structure described by Sm3Ga2Sn3 crystallizes in the orthorhombic Cmcm 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 Ga(1), one Sn(2), and four equivalent Sn(1) atoms. In the second Sm site, Sm(2) is bonded in a 10-coordinate geometry to four equivalent Ga(1), two equivalent Sn(2), and four equivalent Sn(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), one Ga(1), one Sn(2), and two equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), two equivalent Ga(1), and one Sn(2) atom. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to one Sm(1), four equivalent Sm(2), two equivalent Ga(1), and two equivalent Sn(1) atoms. is represented by the CIF card [CIF]
