Molecules of the title compound, C9H8NO+center dot Cl-center dot H2O, are linked into two rings by strong hydrogen bonding via the free water molecules and the Cl- anions. The two hydrogen-bonded rings are joined to give a corrugated chain along [ 001]. Comparisons with other 8-hydroxyquinoline- based salts are also presented, highlighting similar ring structures in a 1: 1 salt with Kemp's triacid (r-1, c-3,c-5- trimethylcyclohexane-1,3,5-tricarboxylic acid) and in 8-hydroxy-1-methylquinolinium chloride monohydrate.
