Nb Cu Tc
NbTcCu crystallizes in the triclinic P1 space group. Nb(1) is bonded in a 9-coordinate geometry to six equivalent Nb(1), one Tc(1), and two equivalent Cu(1) atoms. All Nb(1)-Nb(1) bond lengths are 2.74 Å. The Nb(1)-Tc(1) bond length is 3.46 Å. There is one shorter (2.52 Å) and one longer (2.76 Å) Nb(1)-Cu(1) bond length. Tc(1) is bonded in a 2-coordinate geometry to one Nb(1) and three equivalent Cu(1) atoms. There are a spread of Tc(1)-Cu(1) bond distances ranging from 2.00-2.36 Å. Cu(1) is bonded in a 5-coordinate geometry to two equivalent Nb(1) and three equivalent Tc(1) atoms.
