Molecules of the title compound, C 9 H 8 NO + ·Cl − ·H 2 O, 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.
