WIr2Rh crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WIr2Rh cluster. W(1) is bonded in a 3-coordinate geometry to one Ir(1), one Ir(2), and one Rh(1) atom. The W(1)-Ir(1) bond length is 1.96 Å. The W(1)-Ir(2) bond length is 1.96 Å. The W(1)-Rh(1) bond length is 2.01 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted single-bond geometry to one W(1) atom. In the second Ir site, Ir(2) is bonded in a 2-coordinate geometry to one W(1) and one Rh(1) atom. The Ir(2)-Rh(1) bond length is 1.67 Å. Rh(1) is bonded in a 1-coordinate geometry to one W(1) and one Ir(2) atom.
