Os5Rh is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Os5Rh cluster. There are five inequivalent Os sites. In the first Os site, Os(1) is bonded in a 3-coordinate geometry to one Os(2), one Os(4), and one Rh(1) atom. The Os(1)-Os(2) bond length is 1.73 Å. The Os(1)-Os(4) bond length is 1.90 Å. The Os(1)-Rh(1) bond length is 1.59 Å. In the second Os site, Os(2) is bonded in a 1-coordinate geometry to one Os(1) atom. In the third Os site, Os(3) is bonded in a 1-coordinate geometry to one Os(4) atom. The Os(3)-Os(4) bond length is 1.04 Å. In the fourth Os site, Os(4) is bonded in a 1-coordinate geometry to one Os(1) and one Os(3) atom. In the fifth Os site, Os(5) is bonded in a single-bond geometry to one Rh(1) atom. The Os(5)-Rh(1) bond length is 0.49 Å. Rh(1) is bonded in a distorted single-bond geometry to one Os(1) and one Os(5) atom.
