6-(4-Methyl­phen­yl)-1,3,5-triazine-2,4-di­amine–4-methyl­benzoic acid (1/1)

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...π inter­action is observed.
