Preparation and characterization of potassium difluorodioxobromate and tetrafluoro-oxobromate

Abstract

The compounds K[BrF₂O₂] and K[BrF₄O] have been prepared by the reaction of K[BrO₃] with K[RrF₆]. The reaction of K[BrO₃] with BrF₅ has been reinvestigated and K[BrF₄O₂], K[BrF₂O₂], and BrO₂F have been identified as the products. The Raman spectra of the [BrF₂O₂]^– and [BrF₄O]^– ions have been recorded and tentatively assigned on the basis of C_2v and C_4v symmetry respectively.
