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

The benzoic acid molecule of the title adduct, C10H11N5 center dot C7H6O2, is approximately planar, with a dihedral angle of 7.2 (3)degrees between the carboxylic acid group and the benzene ring. In the triazine molecule, the plane of the triazine ring makes a dihedral angle of 28.85 (9)degrees with that of the adjacent benzene ring. In the crystal, the two components are linked by N-H center dot center dot center dot O and O-H center dot center dot center dot N hydrogen bonds with an R-2(2) (8) motif, thus generating a 1 + 1 unit of triazine and benzoic acid molecules. The acid-base units are further connected by N-H center dot center dot center dot N hydrogen bonds with R22 (8) motifs, forming a supramolecular ribbon along [101]. The crystal structure also features weak pi-pi [centroid-centroid distances = 3.7638 (12) and 3.6008 (12) angstrom] and C-H center dot center dot center dot pi interactions.
