Os2Ru is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Os2Ru clusters. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Os(2) atom. The Os(1)-Os(2) bond length is 0.89 Å. In the second Os site, Os(2) is bonded in a linear geometry to one Os(1) and one Ru(1) atom. The Os(2)-Ru(1) bond length is 0.99 Å. Ru(1) is bonded in a single-bond geometry to one Os(2) atom.
