La La Tc Au
La2TcAu is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2TcAu clusters. There are two inequivalent La sites. In the first La site, La(1) is bonded in a linear geometry to one Tc(1) and one Au(1) atom. The La(1)-Tc(1) bond length is 1.59 Å. The La(1)-Au(1) bond length is 1.45 Å. In the second La site, La(2) is bonded in a single-bond geometry to one Au(1) atom. The La(2)-Au(1) bond length is 1.45 Å. Tc(1) is bonded in a single-bond geometry to one La(1) atom. Au(1) is bonded in a linear geometry to one La(1) and one La(2) atom.
