Homoatomic Zintl ions (for example, [Ge 9 ] 4− ; see picture, left) have long been discussed as precursors for the formation of more complicated structures. The characterization of “□ 24 Ge 136 ” with the (unfilled) clathrate‐II structure (right; orange, gray, yellow: pentagonal dodecahedra, pink: hexakaidecahedra) and other porous germanium‐based materials supports this hypothesis.
