Nb Nb Tc Ru
NbTcNbRu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NbRu cluster and one NbTc cluster. In the NbRu cluster, Nb(2) is bonded in a single-bond geometry to one Ru(1) atom. The Nb(2)-Ru(1) bond length is 1.25 Å. Ru(1) is bonded in a single-bond geometry to one Nb(2) atom. In the NbTc cluster, Nb(1) is bonded in a single-bond geometry to one Tc(1) atom. The Nb(1)-Tc(1) bond length is 1.23 Å. Tc(1) is bonded in a single-bond geometry to one Nb(1) atom.
