Bromine Pentafluoride BrF₅ , the Formation of [BrF₆ ]^- Salts, and the Stereochemical (In)activity of the Bromine Lone Pairs.

ABSTRACT: BrF₅ can be prepared by treating BrF₃ with fluorine under UV light in the region of 300 to 400 nm at room temperature. It was analyzed by UV-Vis, NMR, IR and Raman spectroscopy. Its crystal structure was redetermined by X-ray diffraction, and its space group was corrected to Pnma. Quantum-chemical calculations were performed for the band assignment of the vibrational spectra. A monoclinic polymorph of BrF₅ was quantum chemically predicted and then observed as its low-temperature modification in space group P2₁ /c by single crystal X-ray diffraction. BrF₅ reacts with the alkali metal fluorides AF (A=K, Rb) to form alkali metal hexafluoridobromates(V), A[BrF₆ ] the crystal structures of which have been determined. Both compoun
