Abstract
It was established by X-ray crystallographic analysis that 4,6-dimethyl-2-(phenylhydrazino)pyrimidine forms 2-(2-n-butyl-2-phenylhydrazino)-4,6-dimethylpyrimidine during alkylation with n-butyl bromide and 4,6-dimethyl-2-(phenylhydrazino)-1(H)-pyrimidinium nitrate during protonation with nitric acid. The structure of the molecules and the system of intermolecular hydrogen bonds in the crystals of the compounds are discussed.
