Synthesis and studies on pyridinium pentafluorozirconate and pyridinium oxotetrafluoroniobate

Journal of Fluorine Chemistry, 1994
Abstract Pyridinium pentafluorozirconate, (C5H5NH)ZrF5, and pyridinium oxotetrafluoroniobate, (C5H5NH)NbOF4, have been synthesised by the reaction of pyridinium poly(hydrogen fluoride), PPHF, with ZrOCl2 and Nb2O5, respectively. These new complexes have been characterised by chemical analysis, thermal analysis, X-ray diffraction and infrared spectra.
