Some halopyridinium hexafluoridotitanate salts have been prepared and characterised. Titanium dioxide, which was used for the synthesis of the compounds, was prepared by hydrolysis of titanium(IV) butoxide. The TiO2 thus prepared then reacted with corresponding halopyridine: 2-fluoropyridine, 2-chloropyridine, 2-bromopyridine and 3-bromopyridine. Reactions between TiO2 and halopyridine were carried out in different molar ratio. The resulting products were analysed by infrared spectroscopy, nuclear magnetic resonance spectroscopy, elemental analysis and X-ray structural analysis.
