W4IrCl is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three W4IrCl clusters. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one W(2), two equivalent W(1), and one Ir(1) atom. The W(1)-W(2) bond length is 1.13 Å. Both W(1)-W(1) bond lengths are 0.65 Å. The W(1)-Ir(1) bond length is 1.48 Å. In the second W site, W(2) is bonded in a 4-coordinate geometry to three equivalent W(1) and one Cl(1) atom. The W(2)-Cl(1) bond length is 2.61 Å. Ir(1) is bonded in a 3-coordinate geometry to three equivalent W(1) atoms. Cl(1) is bonded in a distorted single-bond geometry to one W(2) atom.
