title: 2,5-Dicarboxyanilinium chloride monohydrate.
abstract: The title compound, C8H8NO4+.Cl-.H2O, is the chlorohydrated form of 2-aminobenzene-1,4-dicarboxylic acid, the basic crystal structure of which is still not known. Molecules are linked by classical N-H...O, O-H...O, N-H...Cl and O-H...Cl hydrogen bonds, mainly along the molecular plane, into sheets built by unusual R6(4)(26), R6(4)(22) and R4(3)(22) rings. The stacking between layers is stabilized by another N-H...Cl hydrogen bond and by pi-pi interactions between aromatic rings facing each other.
