OsIrCo2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsIrCo2 clusters. Os(1) is bonded in a 2-coordinate geometry to two equivalent Co(1) atoms. Both Os(1)-Co(1) bond lengths are 0.65 Å. Ir(1) is bonded in a 2-coordinate geometry to two equivalent Co(1) atoms. Both Ir(1)-Co(1) bond lengths are 1.33 Å. Co(1) is bonded in a 3-coordinate geometry to one Os(1), one Ir(1), and one Co(1) atom. The Co(1)-Co(1) bond length is 0.71 Å.
