CrIr2In is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrIr2In clusters. Cr(1) is bonded in a 2-coordinate geometry to two equivalent Ir(1) atoms. Both Cr(1)-Ir(1) bond lengths are 0.95 Å. Ir(1) is bonded in a distorted single-bond geometry to one Cr(1), one Ir(1), and one In(1) atom. The Ir(1)-Ir(1) bond length is 0.32 Å. The Ir(1)-In(1) bond length is 0.64 Å. In(1) is bonded in a 2-coordinate geometry to two equivalent Ir(1) atoms.
