YIr2Ni crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one YIr2Ni cluster. Y(1) is bonded in a 1-coordinate geometry to one Ni(1) atom. The Y(1)-Ni(1) bond length is 1.89 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 2-coordinate geometry to one Ir(2) and one Ni(1) atom. The Ir(1)-Ir(2) bond length is 1.07 Å. The Ir(1)-Ni(1) bond length is 2.09 Å. In the second Ir site, Ir(2) is bonded in a 1-coordinate geometry to one Ir(1) atom. Ni(1) is bonded in a 1-coordinate geometry to one Y(1) and one Ir(1) atom.
