Hydrogen bonding in two salts of 3-methylthio-4-(propargylthio)quinoline
In 3-methylthio-4-(propargylthio)quinolinium chloride monohydrate, C(13)H(12)NS(2)(+).Cl(-).H(2)O, and 3-methylthio-4-(propargylthio)quinolinium trichloroacetate, C(13)H(12)NS(2)(+).C(2)Cl(3)O(2)(-), the terminal alkyne group forms C[triple-bond]C-H.O hydrogen bonds of favourable geometry. The conformation of the flexible propargylthio group is different in the two structures.
