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.
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. All Yb(1)-Ir(1) bond lengths are 2.93 Å. In the second Yb site, Yb(2) is bonded in a 5-coordinate geometry to five equivalent Ir(1) atoms. There are a spread of Yb(2)-Ir(1) bond distances ranging from 2.80-3.11 Å. Ir(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms.
