IrBiIr3Bi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ir3Bi cluster and one IrBi cluster. In the Ir3Bi cluster, there are three inequivalent Ir sites. In the first Ir site, Ir(2) is bonded in a distorted bent 150 degrees geometry to one Ir(4) and one Bi(2) atom. The Ir(2)-Ir(4) bond length is 1.02 Å. The Ir(2)-Bi(2) bond length is 1.34 Å. In the second Ir site, Ir(3) is bonded in a distorted single-bond geometry to one Bi(2) atom. The Ir(3)-Bi(2) bond length is 1.34 Å. In the third Ir site, Ir(4) is bonded in a single-bond geometry to one Ir(2) atom. Bi(2) is bonded in an L-shaped geometry to one Ir(2) and one Ir(3) atom. In the IrBi cluster, Ir(1) is bonded in a distorted single-bond geometry to one Bi(1) atom. The Ir(1)-Bi(1) bond length is 0.95 Å. Bi(1) is bonded in a single-bond geometry to one Ir(1) atom.
