摘要：

(Figure Presented) 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 "□24Ge136" with the (unfilled) clathrate-II structure (right; orange, gray, yellow: pentagonal dodecahedra, pink: hexakaidecahedra) and other porous germanium-based materials supports this hypothesis. © 2007 Wiley-VCH Verlag GmbH & Co.
