The crystal structure described by Dy5Si3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. In the second Dy site, Dy(2) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to four equivalent Dy(2) and five equivalent Dy(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
