 Title    2-[N,N-Bis(trimethylstannyl)amino]pyridine and Bis[N-(N-trimethyIsiIyI- 2-aminopyridyI)]dimethyltin -Intramolecular N-Sn Co-ordination  
 Abstract    2-[N,N-Bis(trimethylstannyl)amino]pyridine (1), bis[N-(N-trimethylsilyl-2-aminopyridyl)]-dimethyltin (2) and bis[N-(N-trimethylsilyl-2-amino-3-methyl-pyridyl)]dimethyltin (3) were prepared and characterized by 'H, i3C, l5N, 29Si and ll9Sn NMR spectroscopy. In the case of 1, intramolecular pyridine-N-Sn co-ordination was established by the low temperature ll9Sn NMR spectra which show two resonance signals, one for a penta-co-ordinate and one for a tetra-co-ordinate tin site. In the cases of 2 and 3, intramolecular pyridine-N-Sn co-ordination follows conclusively from l3C, l5N and ll9Sn NMR parameters. In contrast with the known behaviour of the corresponding trimethyltin derivative, the methyl group in 3-position of the pyridine ring does not prevent this type of co-ordination in 3.
