The molecular structures of 1-[chloro(2-methoxyphenyl)methyl]pyridinium chloride and 1-[chloro(3-nitrophenyl)methyl]-pyridinium chloride were studied by X-ray single crystal diffraction and semiempirical calculations (PM3, AM1, and MNDO) in comparison with model compounds to give a deeper insight into reactivity of these pyridinium salts. Feasibility of the nucleophilic substitution of the chlorine
