In the title compounds, 4-carboxy-anilinium (2R,3R)-tartrate, C7H8NO2 +·C4H5O6 -, (I), and 4-amino-benzoic acid, C7H7NO2, (II), the carboxyl planes of the 4-carboxy-anilinium cations/4-amino-benzoic acid are twisted from the aromatic plane. In (I), the characteristic head-to-tail inter-actions are observed through the tartrate anions, forming two C 2 2(7) chain motifs propagating parallel to the a and c axes of the unit cell. Also, the tartrate anions are connected through two primary C 1 1(6) and C 1 1(7) chain motifs, leading to a secondary R 4 4(22) ring motif. In (II), head-to-tail inter-action is seen through a discrete D 1 1(2) motif and carboxyl group dimerization is observed through centrosymmetrically related R 2 2(8) motifs around the inversion centres of the unit cell. The crystal structures of both compounds are stabilized by intricate three-dimensional hydrogen-bonding networks. Alternate hydro-phobic and hydro-philic layers are observed in (I) as a result of a column-like arrangement of the anions and the aromatic rings of the cations.
