Structures of three substituted arenesulfonamides from X-ray powder diffraction data using the differential evolution technique

The crystal structures of three substituted arenesulfonamides have been solved from X-ray powder diffraction data using a new direct-space structure solution method based on a differential evolution algorithm: N—H...O hydrogen bonding leads to supramolecular aggregates in three, two or one dimensions, modified in some cases by C—H...O hydrogen bonds and aromatic π...π stacking interactions.
