La La Ga Au
La2AuGa is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2AuGa clusters. There are two inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one Au(1) atom. The La(1)-Au(1) bond length is 1.36 Å. In the second La site, La(2) is bonded in a single-bond geometry to one Ga(1) atom. The La(2)-Ga(1) bond length is 0.54 Å. Au(1) is bonded in a linear geometry to one La(1) and one Ga(1) atom. The Au(1)-Ga(1) bond length is 1.68 Å. Ga(1) is bonded in a linear geometry to one La(2) and one Au(1) atom.
