W2IrBi crystallizes in the monoclinic Cm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Ir(1) and one Bi(1) atom. The W(1)-Ir(1) bond length is 0.24 Å. The W(1)-Bi(1) bond length is 3.70 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Ir(1) and one Bi(1) atom. The W(2)-Ir(1) bond length is 1.50 Å. The W(2)-Bi(1) bond length is 3.70 Å. Ir(1) is bonded in a distorted single-bond geometry to one W(1) and one W(2) atom. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to one W(1); one W(2); and six Bi(1,1) atoms to form a mixture of corner and edge-sharing BiBi6W2 hexagonal bipyramids. All Bi(1)-Bi(1,1) bond lengths are 3.13 Å. In the second Bi site, Bi(1) is bonded to one W(1); one W(2); and six Bi(1,1) atoms to form a mixture of corner and edge-sharing BiBi6W2 hexagonal bipyramids. The Bi(1)-W(1) bond length is 3.70 Å. The Bi(1)-W(2) bond length is 3.70 Å. Both Bi(1)-Bi(1) bond lengths are 3.13 Å.
