The reaction of BrF5 with a large excess of LiNO3 at 0°C produces LiF, BrONO2, N2O5, and O2 as the principal products. The infrared spectra of BrONO2 in the gas and solid phases and in N2 and Ne matrices and the Raman spectrum of the solid phase were recorded. With the exception of the N-OBr torsional mode, all fundamental vibrations of BrONO2 can be assigned and support a planar structure for this molecule. The fundamental vibrations involving the NO2 group exhibit pronounced frequency shifts on going from the gas to the solid, indicating association in the solid phase. With N2O5 the BrONO2 molecule forms an unstable adduct, which was shown by Raman spectroscopy to possess the ionic structure NO2+[Br(ONO2)2]-. On the basis of a comparison of our results with those found in the literature and in three unpublished dissertations, it is concluded that the previously reported compounds BrO2·3NO2, Br(NO3)3, and BrNO3·N2O5 are all identical with our material and therefore must be assigned the composition NO2+[Br(ONO2)2]-. For comparison, Cs+[Br(ONO2)2]- was also prepared, and its vibrational spectra were recorded and assigned.
