ReOsRh2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReOsRh2 clusters. Re(1) is bonded in a 1-coordinate geometry to one Os(1), one Rh(1), and one Rh(2) atom. The Re(1)-Os(1) bond length is 1.50 Å. The Re(1)-Rh(1) bond length is 1.62 Å. The Re(1)-Rh(2) bond length is 1.27 Å. Os(1) is bonded in a 2-coordinate geometry to one Re(1) and one Rh(1) atom. The Os(1)-Rh(1) bond length is 1.32 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Re(1) and one Os(1) atom. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Re(1) atom.
