An infrared spectral investigation of 2and 4-pyridone hexachloroantimonates and hexachlorostannates is reported. Protonation of these pyridones occurs on oxygen to form the 2and 4hydroxypyridinium ions, as witnessc:d 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 2and 4-substituted pyridinium hr:xachloroantimonates included in this study.Introduction.
