Abstract The structure of the molecule of 4, 6-diamino-3, S-dicvano-2-cyanomethylpyridine is confirmed by the 13C NMR spectrum which, together with the t H and15N NMR spectra (the "complete" NMR spectrum), allows almost unambiguous assignment (with the exception of the virtually coinciding paired signals of the atoms of carbon and nitrogen of the 3- and 5-CN groups). The applicability of the method of increments in the 13C NMR was shown in the assignment of the signals of the carbon atoms in pyridine derivatives. The ratio of the chemical shifts of the nitrogen and hydrogen atoms of the amino groups, known from the literature for aminobenzenes, was confirmed.
