WIrAuIr crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AuIr clusters and two WIr clusters. In each AuIr cluster, Ir(2) is bonded in a single-bond geometry to one Au(1) atom. The Ir(2)-Au(1) bond length is 0.44 Å. Au(1) is bonded in a single-bond geometry to one Ir(2) atom. In each WIr cluster, W(1) is bonded in a single-bond geometry to one Ir(1) atom. The W(1)-Ir(1) bond length is 1.07 Å. Ir(1) is bonded in a single-bond geometry to one W(1) atom.
