ReOsRh2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReOsRh2 clusters. Re(1) is bonded in a distorted L-shaped geometry to two equivalent Rh(1) atoms. Both Re(1)-Rh(1) bond lengths are 0.36 Å. Os(1) is bonded in a distorted L-shaped geometry to two equivalent Rh(1) atoms. Both Os(1)-Rh(1) bond lengths are 0.36 Å. Rh(1) is bonded in a distorted L-shaped geometry to one Re(1) and one Os(1) atom.
