IrB is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one IrB cluster. Ir(1) is bonded in a distorted water-like geometry to one Ir(1) and one B(1) atom. The Ir(1)-Ir(1) bond length is 0.80 Å. The Ir(1)-B(1) bond length is 0.52 Å. B(1) is bonded in a single-bond geometry to one Ir(1) atom.
