Ta Rh Rh Rh Rh Rh
TaRh5 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaRh5 cluster. Ta(1) is bonded in a single-bond geometry to one Rh(3) and one Rh(4) atom. The Ta(1)-Rh(3) bond length is 2.39 Å. The Ta(1)-Rh(4) bond length is 0.87 Å. There are five inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Rh(5) atom. The Rh(1)-Rh(5) bond length is 0.70 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Rh(4) atom. The Rh(2)-Rh(4) bond length is 1.14 Å. In the third Rh site, Rh(3) is bonded in a distorted bent 150 degrees geometry to one Ta(1) and one Rh(5) atom. The Rh(3)-Rh(5) bond length is 0.61 Å. In the fourth Rh site, Rh(4) is bonded in a distorted single-bond geometry to one Ta(1) and one Rh(2) atom. In the fifth Rh site, Rh(5) is bonded in a linear geometry to one Rh(1) and one Rh(3) atom.
