✦ Synopsis
In the title compound, C~6~H~9~N~3~·C~7~H~6~O~3~, the 2-amino-4,6-dimethylpyrimidine and 4-hydroxybenzoic acid molecules link together via N—H...O and O—H...N hydrogen bonds to form an eight-membered R
~2~
^2^(8) ring. Further hydrogen bonds and C—H...O interactions result in the formation of a three-dimensional network.
