OsIrIrAs crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one iridium;osmium molecule and one IrAs cluster. In the IrAs cluster, Ir(2) is bonded in a distorted single-bond geometry to one As(1) atom. The Ir(2)-As(1) bond length is 0.60 Å. As(1) is bonded in a single-bond geometry to one Ir(2) atom.
