OsRh2B crystallizes in the monoclinic Cm space group. Os(1) is bonded in a 1-coordinate geometry to one Rh(1) and one Rh(2) atom. The Os(1)-Rh(1) bond length is 1.53 Å. The Os(1)-Rh(2) bond length is 2.57 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Os(1) and one B(1) atom. The Rh(1)-B(1) bond length is 1.25 Å. In the second Rh site, Rh(2) is bonded in a 8-coordinate geometry to one Os(1), four equivalent Rh(2), and three equivalent B(1) atoms. All Rh(2)-Rh(2) bond lengths are 2.72 Å. There is one shorter (2.53 Å) and two longer (2.91 Å) Rh(2)-B(1) bond lengths. B(1) is bonded in a single-bond geometry to one Rh(1) and three equivalent Rh(2) atoms.
