Crystal structure of 3,4-di-chloro-anilinium hydrogen phthalate.
In the title salt, C6H6Cl2N(+)·C8H5O4 (-), the carb-oxy-lic acid and carboxyl-ate groups of the anion form dihedral angles of 20.79 (19) and 74.76 (14)°, respectively, with the plane of the benzene ring. In the crystal, mol-ecules are assembled into a two-dimensional polymeric network parallel to (100) via N-H⋯O and O-H⋯O hydrogen bonds. In addition, within the layer, there are π-π stacking inter-actions between the benzene rings of the cation and the anion [centroid-centroid distance = 3.6794 (17) Å]. A weak C-H⋯O interaction is also observed.
