MgLa2Ge is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgLa2Ge cluster. Mg(1) is bonded in a distorted bent 150 degrees geometry to one La(1) and one Ge(1) atom. The Mg(1)-La(1) bond length is 0.43 Å. The Mg(1)-Ge(1) bond length is 2.37 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one Mg(1) atom. In the second La site, La(2) is bonded in a single-bond geometry to one Ge(1) atom. The La(2)-Ge(1) bond length is 1.56 Å. Ge(1) is bonded in a bent 150 degrees geometry to one Mg(1) and one La(2) atom.
