Nb Nb Tc Rh
Nb2TcRh crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Nb2TcRh cluster. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a single-bond geometry to one Tc(1) atom. The Nb(1)-Tc(1) bond length is 0.90 Å. In the second Nb site, Nb(2) is bonded in a distorted single-bond geometry to one Rh(1) atom. The Nb(2)-Rh(1) bond length is 2.03 Å. Tc(1) is bonded in a distorted single-bond geometry to one Nb(1) and one Rh(1) atom. The Tc(1)-Rh(1) bond length is 1.88 Å. Rh(1) is bonded in a 2-coordinate geometry to one Nb(2) and one Tc(1) atom.
