- Abstract
Metastable Ge( cF136) with empty clathrate-II crystal structure was successfully used for the preparation of otherwise hardly accessible germanium clathrate phases. On reaction of Ge( cF136) with potassium vapour at 280 °C for 6 days, the new clathrate-II phase K24Ge136 was formed, in which the cages of the germanium framework are completely filled by potassium atoms. The crystal structure of K xGe136 is discussed for different potassium contents ( x=0, 8.6, 24).
