TaOsRh2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaOsRh2 cluster. Ta(1) is bonded in a 2-coordinate geometry to one Os(1) and one Rh(2) atom. The Ta(1)-Os(1) bond length is 0.42 Å. The Ta(1)-Rh(2) bond length is 0.42 Å. Os(1) is bonded in a single-bond geometry to one Ta(1), one Rh(1), and one Rh(2) atom. The Os(1)-Rh(1) bond length is 0.29 Å. The Os(1)-Rh(2) bond length is 0.12 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 Rh(2) atom. The Rh(1)-Rh(2) bond length is 0.29 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Ta(1), one Os(1), and one Rh(1) atom.
