TaRh2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaRh2 cluster. Ta(1) is bonded in a 1-coordinate geometry to one Rh(1) and one Rh(2) atom. The Ta(1)-Rh(1) bond length is 1.29 Å. The Ta(1)-Rh(2) bond length is 2.03 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted single-bond geometry to one Ta(1) atom. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Ta(1) atom.
