WIrZn2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WIrZn2 clusters. W(1) is bonded in a 2-coordinate geometry to two equivalent Zn(1) atoms. Both W(1)-Zn(1) bond lengths are 0.99 Å. Ir(1) is bonded in an L-shaped geometry to two equivalent Zn(1) atoms. Both Ir(1)-Zn(1) bond lengths are 0.41 Å. Zn(1) is bonded in a distorted single-bond geometry to one W(1) and one Ir(1) atom.
