Abstract: In the title hydrated molecular salt, C5H7N2+·C7H3ClNO4-·H2O, the ions and water molecules assemble into ribbons of R65(22) rings along the c axis via O(water)-HO-, N+-HO(water) and N-HO- hydrogen bonds. N-HO- hydrogen bonds connect adjacent ribbons along the c-axis direction via R44(12) rings, forming hydrogen-bonded layers. The CO2 and NO2 groups make dihedral angles of 81.8 (2) and 1.4 (2)°, respectively, with the ring in the anion.
