The molecules of the title compound, C6H4ClNO2, are almost completely planar. Hydrogen bonds of the form O—H
N interconnect the molecules to form infinite chains, which are also planar and which are packed face-to-face to form well defined layers of molecules.

In the structure of the title salt, C12H10N3O+·Cl-·3H2O, the only species which do not coincide with the mirror plane in the space group P63/m are one complete water molecule, one H atom of another water molecule and two H atoms of the methyl group of the cation. Consequently, apart from the two H atoms of the methyl group, the cation is completely planar. The hydrogen bonding between the water molecules and, through Cl- anions, to the cations, although extensive, can be modelled satisfactorily only by treating one H atom in each of the two types of water molecules as disordered.
