Zusammenfassung:Under pressure: The new modification Ge(hR8) is obtained upon pressurization of clathrate‐type Ge(cF136) or controlled decompression of a Ge(tI4)‐type high‐pressure phase. The atomic arrangement comprises four‐bonded germanium atoms with a topological organization bearing remarkable similarity to high‐pressure host–guest assemblies of other main‐group elements.
