The structure described by Sc5Sn3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. In the second Sc site, Sc(2) is bonded in a 5-coordinate geometry to five equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Sc(1) and five equivalent Sc(2) atoms. is represented by the CIF file [CIF]
