Synthesis and studies on pyridinium chlorofluoro complexes of indium and bismuth

Abstract Pyridinium trichlorotrifluoroindate, (C 5 H 5 NH) 3 InCl 3 F 3 , and pyridinium trichlorofluorobismuthate, C 5 H 5 NHBiCl 3 F, have been synthesised by the reaction of pyridinium poly (hydrogen fluoride), PPHF, with InCl 3 and BiCl 3 , respectively. These new complexes have been characterised by chemical and thermal analysis, NMR ( 1 H and 19 F) and infrared spectroscopy, and powder X-ray diffraction methods.
