چکیده
In the title 1:1 adduct, C(6)H(9)N(3)·C(7)H(7)NO(2), the crystal structure is stabilized by hydrogen bonds involving two different R(2) (2)(8) motifs. One of them is formed by the inter-action of 2-amino-4,6-dimethyl-pyrimidine (AMPY) with the carboxyl group of anthranilic acid (AA) through N-H⋯O and O-H⋯N hydrogen bonds, whereas the other is formed through the inter-action of two centrosymmetrically related pyrimidines involving N-H⋯N hydrogen bonds. These two combined motifs form a heterotetra-mer. The heterotetra-mer sheets are stacked into three-dimensional network.

The crystal of the title compound, C(6)H(9)N(3)·C(7)H(6)O(2), contains tetra-meric hydrogen-bonded units comprising a central pair of 2-amino-pyrimidine mol-ecules linked across a centre of inversion by N-H⋯N hydrogen bonds and two pendant benzoic acid mol-ecules attached through N-H⋯O and O-H⋯N hydrogen bonds. These hydrogen-bonded units are arranged into layers in (002).
