The compound described by Sm3Co4Sn13 crystallizes in the cubic Pm-3n space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Co(1) and twelve equivalent Sn(2) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(2) is bonded in a 9-coordinate geometry to three equivalent Sm(1), two equivalent Co(1), one Sn(1), and three equivalent Sn(2) atoms. In the second Sn site, Sn(1) is bonded in a cuboctahedral geometry to twelve equivalent Sn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
