In the title hydrated mol-ecular salt, C5H7N2(+)·C7H3ClNO4(-)·H2O, the ions and water mol-ecules assemble into ribbons of R6(5)(22) rings along the c axis via O(water)-H⋯O(-), N(+)-H⋯O(water) and N-H⋯O(-) hydrogen bonds. N-H⋯O(-) hydrogen bonds connect adjacent ribbons along the c-axis direction via R4(4)(12) rings, forming hydrogen-bonded layers. The CO2 and NO2 groups make dihedral angles of ...

In the title Schiff base compound, C(13)H(9)Cl(2)NO, the mol-ecule displays an E conformation about the imine C=N double bond, with a dihedral angle of 8.09 (11)° between the two benzene rings. In the crystal, mol-ecules are linked by a single O-H⋯O hydrogen bond, giving one-dimensional chains which extend along (100).
