Abstract: In the title 1:1 adduct, C6H9N3·C7H7NO2, the crystal structure is stabilized by hydrogen bonds involving two different R22(8) motifs. One of them is formed by the interaction of 2-amino-4,6-dimethylpyrimidine (AMPY) with the carboxyl group of anthranilic acid (AA) through N-H
O and O-HN hydrogen bonds, whereas the other is formed through the interaction of two centrosymmetrically related pyrimidines involving N-HN hydrogen bonds. These two combined motifs form a heterotetramer. The heterotetramer sheets are stacked into three-dimensional network.
