(Zn)2AlGe is Cubic alpha N2-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AlGe cluster and one zinc molecule. In the AlGe cluster, Al(1) is bonded in a single-bond geometry to one Ge(1) atom. The Al(1)-Ge(1) bond length is 0.64 Å. Ge(1) is bonded in a single-bond geometry to one Al(1) atom.
