An infrared spectral investigation of 2– and 4‐pyridone hexachloroantimonates and hexachlorostannates is reported. Protonation of these pyridones occurs on oxygen to form the 2‐ and 4‐hydroxypyridinium ions, as witnessed by the presence of both OH and NH stretching bands. Aromatic ring and skeletal frequencies in these cations correlated very well with those found in other 2– and 4‐substituted pyridinium hexachloroantimonates included in this study.
