IrTa(Ga)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two digallane molecules and two IrTa clusters. In each IrTa cluster, Ta(1) is bonded in a single-bond geometry to one Ir(1) atom. The Ta(1)-Ir(1) bond length is 1.09 Å. Ir(1) is bonded in a single-bond geometry to one Ta(1) atom.
