TcIrB crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcIrB clusters. Tc(1) is bonded in a single-bond geometry to one B(1) atom. The Tc(1)-B(1) bond length is 1.61 Å. Ir(1) is bonded in a single-bond geometry to one B(1) atom. The Ir(1)-B(1) bond length is 0.12 Å. B(1) is bonded in a distorted single-bond geometry to one Tc(1) and one Ir(1) atom.
