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—H⋯O and O—H⋯N hydrogen bonds, forming a centrosymmetric 2 + 2 unit with R 2 2(8) and R 4 2(8) motifs. These units are further linked through a pair of N—H⋯N hydrogen bonds into a tape structure along [1-20]. The crystal structure also features weak π–π [centroid–centroid distance = 3.5984 (11) Å] and C—H⋯π interactions.
