IrSiBi is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one IrSiBi cluster. Ir(1) is bonded in a distorted water-like geometry to one Si(1) and one Bi(1) atom. The Ir(1)-Si(1) bond length is 1.27 Å. The Ir(1)-Bi(1) bond length is 0.42 Å. Si(1) is bonded in a distorted single-bond geometry to one Ir(1) atom. Bi(1) is bonded in a single-bond geometry to one Ir(1) atom.
