The crystal structure described by Eu5Sb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. In the second Eu site, Eu(2) is bonded in a 5-coordinate geometry to five equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1) and five equivalent Eu(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
