Abstract

Abstract Pyridinium hexafluorotitanate, (C5H5NH)2TiF6, has been prepared by the reaction of titanium metal with pyridinium poly (hydrogen fluoride), PPHF, at room temperature. Making use of (C5H5NH)2TiF6 as a precursor, ammonium and alkali metal hexafluorotitanates, M2TiF6 (M=NH4, Na, K., Rb and Cs) have been synthesized by metathesis. These hexafluorotitanates have been characterized by chemical analyses, infrared and NMR (1H and 19F) spectroscopy and powder X-ray diffraction methods. Indexed powder X-ray diffraction data for Rb2TiF6 and Cs2TiFg have been reported.
