The structures of 4-methylpyridinium chloride, C6H8N+.Cl-, (I), 3-methylpyridinium chloride, C6H8N+.Cl-, (II), and 3-methylpyridinium bromide, C6H8N+.Br-, (III), have been determined. In all three cases, there is a hydrogen bond between the halogen atom and the protonated N atom. Furthermore, the packing is stabilized by several C-H
halogen contacts. It is remarkable that neither (II) and (III), nor (I) and 4-methylpyridine hydrobromide are isostructural.
