On Thio-, Selenido-, and Telluridogermanates (III): K6Ge2S6, K6Ge2Se6, and Na6Ge2Te6The new compounds K6Ge2S6 and K6Ge2Se6 crystallize in the monoclinic system, space group C2/m (No 12); lattice constants see “Inhaltsübersicht”. The compounds are isotypic and form the K6Si2Te6 structure.Na6Ge2Te6 crystallizes in the K6Sn2Te6 structure, monoclinic, space group P21/c (No 14); lattice constants see “Inhaltsübersicht”.
