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.
