Two 1:1 proton-transfer complexes of sulfobenzoic acids with aromatic amines, namely 4-[2-(4-pyrid-yl)ethen-yl]pyridinium 2-carboxy-benzene-sulfonate, C12H11N2 +·C7H5O5S-, (I), and 1,10-phenanthrolin- 1-ium 4-carboxy-benzene-sulfonate dihydrate, C12H9N2 +· C7H5O5S-·2H2O, (II), have very different hydrogen-bonding patterns compared with reported organic sulfobenzoic acid complexes. In (I), two cations and two anions form a four-mol-ecule loop, in which π-π inter-actions occur. In (II), the anions and water mol-ecules form a three-dimensional hydrogen-bonding network, while the cations only act as pendant components. The water mol-ecules play a central role in the formation of the abundant hydrogen-bonding architecture in (II). The relative poorness and richness of hydrogen bonds in (I) and (II), respectively, give rise to novel hydrogen-bonding patterns. International Union of Crystallography 2007.
