This paper briefly summarises recent investigation of the N-Sn intramolecular donor-acceptor interaction on three sets of compounds - {2-[(dimethylamino)methyl]phenyl}stannanes, [8-(dimethylamino)-1-naphthyl]stannanes and {2,6-bis[(dimethylamino)methyl]phenyl}stannanes using ¹¹⁹Sn, ¹⁵N, ¹³C and ¹H NMR spectroscopy in solution, ¹¹⁹Sn, ¹⁵N, ¹³C CP/MAS NMR spectroscopy and solid-state X-ray diffraction techniques.
