4-Chloro­anilinium 2-carb­oxy-4,5-dichloro­benzoate

The structure of the 1:1 proton-transfer compound of 4-chloro­aniline with 4,5-dichloro­phthalic acid (DCPA), viz. C(6)H(7)ClN(+)·C(8)H(3)Cl(2)O(4) (−), has been determined at 130 K. The non-planar hydrogen phthalate anions and the 4-chloro­anilinium cations form two-dimensional O—H⋯O and N—H⋯O hydr...

description The structure of the 1:1 proton-transfer compound of 4-chloro­aniline with 4,5-dichloro­phthalic acid (DCPA), viz. C(6)H(7)ClN(+)·C(8)H(3)Cl(2)O(4) (−), has been determined at 130 K. The non-planar hydrogen phthalate anions and the 4-chloro­anilinium cations form two-dimensional O—H⋯O and N—H⋯O hydrogen-bonded substructures which have no peripheral extension. Between the sheets there are weak π–π associations between alternating cation–anion aromatic ring systems [shortest centroid–centroid separation = 3.735 (4) Å].
