Tris(dimethylchlorostannyl)amine ( 2a ) reacts with pyridine in a 3:4 molar ratio to produce the tin‐nitrogen containing bicyclo[3.1.1]heptane ( 3 ) with elimination of the adduct Me 2 SnCl 2 ·2 py. Treatment of the distannylamine 2,6‐[Pr 2 H 3 N(SnMe 2 Cl) 2 ( 4 ) with pyridine, however, leads to the formation of the 1:1 pyridine adduct 4 and this can be regarded as a model to explain the route to 3 . The molecular structures of 3 and 5 were determined by multinuclear magnetic resonance spectroscopy in solution, as well as by X‐ray structure analysis of their crystals. Typical structural features for both compounds are intramolecular SnXSn bridges. Support for the structures comes from MS fragmentation patterns, IR spectra, and the Mössbauer spectra.
