Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The accessibility of triads with deltahedral Zintl clusters in analogy to fullerene–linker–fullerene triads is another example for the close relationship between fullerenes and Zintl clusters. The compound {[K(2.2.2‐crypt)]₄[RGe₉‐CHCHCHCH‐Ge₉R]}(toluene)₂ (R=(2<italic>Z</italic>, 4<italic>E</italic>)‐7‐amino‐5‐aza‐hepta‐2, 4‐dien‐2‐yl), containing two deltahedral [Ge₉] clusters linked by a conjugated (1<italic>Z</italic>, 3<italic>Z</italic>)‐buta‐1, 3‐dien‐1, 4‐diyl bridge, was synthesized through the reaction of 1, 4‐bis(trimethylsilyl)butadiyne with K₄Ge₉ in ethylenediamine and crystallized after the addition of 2.2.2‐cryptand and toluene. The compound was characterized by single‐crystal structure analysis as well asNMR and IR spectroscopy.</p> </abstract>
