  • Beschreibung: <jats:p>Four donor/acceptor complexes between halide anion donors and the tetraiodoethene acceptor molecule with tetra(n-butyl)ammoniumcountercations, {(H<jats:sub>9</jats:sub>C<jats:sub>4</jats:sub>)<jats:sub>4</jats:sub>N<jats:sup>⊕</jats:sup>X<jats:sup>⊖</jats:sup>···I<jats:sub>2</jats:sub>C=CI<jats:sub>2</jats:sub>)} (X<jats:sup>⊖</jats:sup> = Cl<jats:sup>⊖</jats:sup>, Br<jats:sup>⊖</jats:sup>, I<jats:sup>⊖</jats:sup>, SCN<jats:sup>⊖</jats:sup>) could be crystallized from acetone solutions of the components R<jats:sub>4</jats:sub>N<jats:sup>⊕</jats:sup>X<jats:sup>⊖</jats:sup> and I<jats:sub>2</jats:sub>C=CI<jats:sub>2</jats:sub> by using low gradient techniques, and their structures determined at low temperature. Their molecule packing motif are layers of halide anion/tetraiodoethene patterns, which are penetrated by one of the four R<jats:sub>4</jats:sub>N<jats:sup>⊕</jats:sup> n-butyl chains. The structure comparison, including analogous ones from an extensive Cambridge Structural Database search, discusses the geminal or vicinal addition to dimer subunits {X<jats:sup>⊖</jats:sup>···I<jats:sub>2</jats:sub>C=CI<jats:sub>2</jats:sub>}<jats:sub>2</jats:sub> as well as their ribbon formation via additional contacts X<jats:sup>⊖</jats:sup>···I, and the effects of the voluminous R<jats:sub>4</jats:sub>N<jats:sup>⊕</jats:sup> countercations. Altogether some light is shedded on essential facets of the fascinating self-assembly comprising an electron-rich halide anion and a polyiodo acceptor molecule.</jats:p>
