(Re)2Ru(Os) crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two rhenium molecules and two Ru(Os) clusters. In each Ru(Os) cluster, Os(1) is bonded in a distorted single-bond geometry to one Ru(1) atom. The Os(1)-Ru(1) bond length is 0.92 Å. Ru(1) is bonded in a distorted single-bond geometry to one Os(1) atom.
