A new complex K_0.5[K(18-crown-6)]_1.5Ge₉·1.5en (1) which contains unprecedented "up" and "down" chain arrangement of unit [-(Ge₉-K-Ge₉)^3--] has been prepared by the reaction of K4Ge9 with HgS in ethylenediamine (en) in the presence of 18-crown-6(1,4,7,10,13,16-hexaoxacyclooctadecane), and characterized by X-ray structure analysis. The color of the title crystals (black), which is darker than that of the reported three compounds with chains of germanium clusters, may result from the naked K⁺ and their interactions with the chain. And the structure differences between 1 and the reported three compounds with chains of germanium have also been discussed.
