La3Ge crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La3Ge clusters. There are three inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one Ge(1) atom. The La(1)-Ge(1) bond length is 0.75 Å. In the second La site, La(2) is bonded in a single-bond geometry to one La(3) and one Ge(1) atom. The La(2)-La(3) bond length is 2.43 Å. The La(2)-Ge(1) bond length is 1.68 Å. In the third La site, La(3) is bonded in a single-bond geometry to one La(2) atom. Ge(1) is bonded in a linear geometry to one La(1) and one La(2) atom.
