Abstract: The 4-methylbenzoic acid molecule of the title adduct, C10H11N5·C8H8O2, is approximately planar with a dihedral angle of 6.3 (2)° between the carboxylic acid group and the benzene ring. In the triazine molecule, the plane of the triazine ring makes a dihedral angle of 29.2 (2)° with that of the adjacent benzene ring. In the crystal, the acid and base molecules are linked via N-H...O and O-H...N hydrogen bonds with an R22(8) motif, and the acid-base pairs are further connected via N-H...N hydrogen bonds with R22(8) motifs, forming a supramolecular ribbon along [101]. Between the tapes, a weak C-H...[pi] interaction is observed.
