The structure described by Sm3(MnSn)4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded to two equivalent Sn(1) and four equivalent Sn(2) atoms to form edge-sharing SmSn6 octahedra. In the second Sm site, Sm(2) is bonded in a 12-coordinate geometry to six equivalent Mn(1), two equivalent Sn(1), and four equivalent Sn(2) atoms. Mn(1) is bonded in a 4-coordinate geometry to three equivalent Sm(2), one Sn(2), and three 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 one Sm(1), two equivalent Sm(2), and six equivalent Mn(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), two equivalent Mn(1), and one Sn(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
