PtAuIr is Cyanogen Chloride-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PtAuIr cluster. Ir(1) is bonded in a single-bond geometry to one Pt(1) atom. The Ir(1)-Pt(1) bond length is 0.01 Å. Pt(1) is bonded in a linear geometry to one Ir(1) and one Au(1) atom. The Pt(1)-Au(1) bond length is 0.85 Å. Au(1) is bonded in a single-bond geometry to one Pt(1) atom.
