IrZnPb is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one IrZnPb cluster. Ir(1) is bonded in a 1-coordinate geometry to one Zn(1) atom. The Ir(1)-Zn(1) bond length is 1.94 Å. Zn(1) is bonded in a 2-coordinate geometry to one Ir(1) and one Pb(1) atom. The Zn(1)-Pb(1) bond length is 1.51 Å. Pb(1) is bonded in a distorted single-bond geometry to one Zn(1) atom.
