The crystal structure described by Yb5Ir3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 6-coordinate geometry to six equivalent Ir(1) atoms. In the second Yb site, Yb(2) is bonded in a 5-coordinate geometry to five equivalent Ir(1) atoms. Ir(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
