Ir2AuZn is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ir2AuZn clusters. Ir(1) is bonded in a distorted single-bond geometry to one Ir(1), one Au(1), and one Zn(1) atom. The Ir(1)-Ir(1) bond length is 0.15 Å. The Ir(1)-Au(1) bond length is 0.26 Å. The Ir(1)-Zn(1) bond length is 0.12 Å. Au(1) is bonded in a 2-coordinate geometry to two equivalent Ir(1) atoms. Zn(1) is bonded in a distorted L-shaped geometry to two equivalent Ir(1) atoms.
