VTcRh2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two VTcRh2 clusters. V(1) is bonded in a distorted linear geometry to one Tc(1) and one Rh(2) atom. The V(1)-Tc(1) bond length is 2.07 Å. The V(1)-Rh(2) bond length is 1.84 Å. Tc(1) is bonded in a single-bond geometry to one V(1) atom. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Rh(2) atom. The Rh(1)-Rh(2) bond length is 1.14 Å. In the second Rh site, Rh(2) is bonded in a linear geometry to one V(1) and one Rh(1) atom.
