1-[(4-Chlorobenzoyl)methyl]-4-(N,N-dimethylamino)pyridinium bromide sesquihydrate and 1-[(4-bromobenzoyl)methyl]-4-(N,N-dimethylamino)pyridinium bromide sesquihydrate.
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-H...O and O-H...Br interactions, as well as weak intramolecular C-H...O interactions. The H2OBr- units form an extended water-bromide chain, with a bridging water molecule on a twofold axis.
