Reactions of Fluorine Nitrate with Lewis Acids

Abstract

FNO3 reacts with BF3, PF5, AsF5 and SbF5, to form white solids identified as nitryl salts of general formula NO2+X−. Molecular oxygen is released during the reaction. The structure of these solids and identification of the oxygen were supported by the Raman spectra, gas pressure measurements and molecular weight.

On Tetrafluorobromates(III): Crystal Structures of the Dibromate CsBr2F7 and the Monobromate CsBrF4

“…Interestingly, KBrF 4 and KAuF 4 were reported to be isostructural. [13] From CsBrF 4 a Raman spectrum was obtained, [1,16] and a powder pattern has been reported, from which it was deduced that the compound should crystallize tetragonal primitive with a unit cell not in accord with MBrF 4 (M = Na, K, Rb). [7] We show later that CsBrF 4 crystallizes in the orthorhombic crystal system isotypic to CsAuF 4 .…”
