The material described by Tb5Sn3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. In the second Tb site, Tb(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 Tb(1) and five equivalent Tb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
