 Title    Ditelluridogermanaten(IV) der Alkalimetalle K -C s M ethanolotherm al Synthesis and Crystal Structure of Diselenido-and Ditelluridogerm anates(IV ) of the Alkali Metals K -C s  
 Abstract    Methanolothermal reaction of M2C 0 3 (M = K, Rb) with Ge and Se yields respectively the diselenidogerm anates(IV) K2G eS e4 and Rb2G eSe4, both of which contain chain anions ro[GeSe42_] in which G eS e4 tetrahedra are linked via S e -S e bonds. A similar structural principle is found in the ditelluridogermanates(IV) Rb2GeTe4 and Cs2GeTe4, prepared by reaction of M2C 0 3 (M = Rb, Cs) with Ge and Te in methanol at temperatures o f respectively 200 and 160 °C. The effect of cation size on the chain conformation is discussed. Rb4G e4S eU)CH3O H , which is formed together with Rb2G eSe4, exhibits isolated anions [G e4S e 10]4_ with an adamantane-like structure.
