2-Amino-4,6-dimethylpyrimidin-1-ium chloride

Abstract

In the title compound, C6H10N3+·Cl−, the cation is essentially planar with an r.m.s. deviations of the fitted atoms of 0.008 Å. In the crystal, adjacent ions are linked by weak N—H...Cl hydrogen bonds involving the pyrimidine and amine N atoms, forming a three-dimensional network. C—H...π interactions between the methyl and pyrimidine groups and π–π stacking [centroid–centroid distance = 3.474 (1) Å] between parallel pyrimidine ring systems are also observed.
