The structure of the 1:1 proton-transfer compound of 4-chloro-aniline with 4,5-dichloro-phthalic 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-chloro-anilinium 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].
4-氯苯胺与4,5-二氯邻苯二甲酸（DCPA）的1:1质子转移化合物，即C(6)H(7)ClN(+)·C(8)H(3)Cl(2)O(4) (-)的结构已在130 K下测定。非平面邻苯二甲酸氢根阴离子和4-氯苯胺阳离子形成二维O-H⋯O和N-H⋯O氢键子结构，且没有外围延伸。在这些片层之间，交替的阳离子-阴离子芳香环系统之间存在弱π-π缔合[最短质心-质心间距 = 3.735 (4) Å]。
