The material described by Na2AlGe2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Na2AlGe2 cluster. Na(1) is bonded in a distorted single-bond geometry to one Ge(1) atom. Al(1) is bonded in a distorted linear geometry to two equivalent Ge(1) atoms. Ge(1) is bonded in a distorted linear geometry to one Na(1) and one Al(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
