Abstract: The title compounds, C₁₅H₁₆ClN₂O⁺·Br^-·1.5H₂O and C₁₅H₁₆BrN₂O⁺·Br^-·1.5H₂O, are isomorphous. The benzene ring is oriented nearly normal to the pyridine ring in both compounds. The molecular packing is mainly influenced by intermolecular O-HO and O-HBr interactions, as well as weak intramolecular C-HO interactions. The H₂OBr^- units form an extended water-bromide chain, with a bridging water molecule on a twofold axis.

Formula: C₁₅H₁₆ClN₂O⁺·Br^-·1.5H₂O and C₁₅H₁₆BrN₂O⁺·Br^-·1.5H₂O
