Extending the electron system of Zintl clusters. Homoatomic deltahedral tetrel clusters are stable with various charges. The linking of these clusters with conjugated bridges and an extension of the resulting π-electronic system opens the potential for “Zintl triads” in analogy to the known fullerene-based triads. The attachment of organic tethers and the addition of supplementary functionalities to the two Ge9 Zintl clusters linked by a conjugated organic buta-1,3-diene-1,4-diyl bridge was realized by the reaction of [Ge9]4− with 1,4-bis(trimethylsilyl)butadiyne and bis(trimethylsilyl)acetylene or (3Z/3E)-7-amino-1-(trimethylsilyl)-5-azahepta-3-en-1-yne in ethylenediamine. The products have been characterized by means of single-crystal structure analysis as well as NMR and Raman spectroscopy.
