Hf Cu Cu Tc
HfTcCu2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfTcCu2 clusters. Hf(1) is bonded in a linear geometry to one Tc(1) and one Cu(2) atom. The Hf(1)-Tc(1) bond length is 1.48 Å. The Hf(1)-Cu(2) bond length is 1.85 Å. Tc(1) is bonded in a linear geometry to one Hf(1) and one Cu(1) atom. The Tc(1)-Cu(1) bond length is 0.36 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one Tc(1) atom. In the second Cu site, Cu(2) is bonded in a single-bond geometry to one Hf(1) atom.
