Anti-inflammatory drugs. X. Hydrated pyrrolidinium {2-[(2,6-dichlorophenyl)amino]phenyl}acetate (HP . D . H2O)

In the solid-state structure of the title compound, C4H10N+·C14H10Cl2NO2-·H2O, the asymmetric unit contains one cation, one anion and a water molecule. There is a network of hydrogen bonds which is similar to that found in the hydrated diethylammonium diclofenac salt. A comparison is made of the molecular conformation of the anions in the two related structures.
