    Description / Table of Contents: The Crystal Structure of Me3SiI · β-Picoline and Me3SiI · γ-Picoline A Comparison between the Lewis-Bases Pyridine, β-Picoline, and γ-PicolineThe reaction of Iodinetrimethylsilane with β- und γ-Picoline (Pic) leads to solid 1 : 1 compounds Me3SiI · β-Picoline 1, Me3SiI · γ-Picoline 2. The reaction was performed at room temperature. Yellow single crystals were obtained by sublimation. Single crystal X-ray investigations confirm that both compounds are ionic [Me3SiPic]+I-. The comparison of β-Picoline with γ-Picoline and Pyridine (Py) demonstrates that the presence of a methyl group and also its position has no significant influence on the Si—N bond length in compound 1, 2 and on the adduct Me3SiI · Py.
    Notes: Iodtrimethylsilan reagiert mit β- und γ-Picolin (Pic) bei Raumtemperatur zu festen 1 : 1 Addukten (M3SiI · β-Picolin 1, Me3SiI · γ-Picolin 2), die durch Sublimation leicht gelblich gefärbte Einkristalle bilden. Die Röntgenstrukturanalyse beider Verbindungen beweist eine ionische Struktur des Typs [Me3SiPic]+ I-. Der Vergleich von β-Picolin mit γ-Picolin und Pyridin (Py) zeigt, daß die Anwesenheit einer Methylgruppe und auch deren Position keinen signifikanten Einfluß auf die Si—N-Bindungslänge in Verbindung 1, 2 und dem Addukt Me3SiI · Py hat.
