Cu Tc Tc Ni
Tc2NiCu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Tc2NiCu cluster. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a distorted single-bond geometry to one Ni(1) atom. The Tc(1)-Ni(1) bond length is 0.93 Å. In the second Tc site, Tc(2) is bonded in a distorted single-bond geometry to one Cu(1) atom. The Tc(2)-Cu(1) bond length is 0.92 Å. Ni(1) is bonded in a distorted L-shaped geometry to one Tc(1) and one Cu(1) atom. The Ni(1)-Cu(1) bond length is 1.34 Å. Cu(1) is bonded in a distorted L-shaped geometry to one Tc(2) and one Ni(1) atom.
