VTcNi2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two VTcNi2 clusters. V(1) is bonded in a single-bond geometry to one Tc(1) and one Ni(2) atom. The V(1)-Tc(1) bond length is 1.59 Å. The V(1)-Ni(2) bond length is 0.07 Å. Tc(1) is bonded in a distorted single-bond geometry to one V(1) atom. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted single-bond geometry to one Ni(2) atom. The Ni(1)-Ni(2) bond length is 1.91 Å. In the second Ni site, Ni(2) is bonded in a single-bond geometry to one V(1) and one Ni(1) atom.
