Abstract: The benzoic acid molecule of the title compound, C4H5ClN4·C7H6O2, is approximately planar, with a dihedral angle of 1.28 (9)° between the carboxy group and the benzene ring. In the crystal, two acid and two base molecules are linked through N-HO and O-HN hydrogen bonds, forming a centrosymmetric 2 + 2 unit with R22(8) and R42(8) motifs. These units are further linked through a pair of N-HN hydrogen bonds into a tape structure along [1-20]. The crystal structure also features weak - [centroid-centroid distance = 3.5984 (11) Å] and C-H interactions.
