Os Os Rh Br Br
Os2RhBr2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Os2RhBr2 clusters. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 3-coordinate geometry to one Rh(1) and two equivalent Br(1) atoms. The Os(1)-Rh(1) bond length is 0.40 Å. Both Os(1)-Br(1) bond lengths are 0.35 Å. In the second Os site, Os(2) is bonded in a 2-coordinate geometry to two equivalent Br(1) atoms. Both Os(2)-Br(1) bond lengths are 1.40 Å. Rh(1) is bonded in a single-bond geometry to one Os(1) atom. Br(1) is bonded in a 2-coordinate geometry to one Os(1), one Os(2), and one Br(1) atom. The Br(1)-Br(1) bond length is 0.12 Å.
