The crystal structure of anhydrous bis(benzylaminium) 5-sulfonatosalicylate, 2C7H10N+·C7H4O6S2−, from the reaction of benzylamine with 5-sulfosalicylic acid, shows the presence of a dianionic 5-sulfonatosalicylate species, uncommon among proton-transfer compounds of this acid with organic Lewis bases. Hydrogen-bonding interactions between both aminium N+—H groups of the two cations and both the sulfonate and carboxylate O-atom acceptors of the anions give a layered two-dimensional network structure.

The Common

The Patterson techniques, recently developed by the same authors for theab initiocrystal structure solution of proteins, have been applied to single and multiple anomalous diffraction (SAD and MAD) data to find the substructure of the anomalous scatterers. An automatic procedure has been applied to a large set of test structures, some of which were originally solved with remarkable difficulty. In all cases, the procedure automatically leads to interpretable electron density maps. Patterson techniques have been compared with direct methods; the former seem to be more efficient than the latter, so confirming the results obtained forab initiophasing, and disproving the common belief that they could only be applied to determine large equal-atom substructures with difficulty.

In the crystal structure of the title organic proton-transfer complex, 2C12H11N2 +·C7H4O5S2−·3H2O, the cations form one-dimensional chains via intermolecular N—H...N hydrogen bonds and these chains, in turn, form a two-dimensional network through π–π stacking interactions. In addition, the anions and water molecules are connected into a two-dimensional hydrogen-bonded network through intermolecular O—H...O hydrogen bonds. The two motifs result in sheets of cations and anions stacked alternately.
