“…Their full oxidizing potential only unfolds upon heating to approximately 200–450 °C, depending on the counter cation and the reducing agent 4. LiBrF 4 is yet unknown,5–7 but X‐ray diffraction data indicate that MBrF 4 (M = Na,8 K,8–14 Rb,8,15,16 NO13) are isostructural and crystallize tetragonally. KBrF 4 and KAuF 4 are isostructural 14.…”

Alkali and alkaline earth metal tetrafluoridobromates MIBrF4, MII(BrF4)2 (MI = Na–Cs, MII = Sr, Ba) can be synthesized from the respective fluorides and BrF3. The reaction of BaF2 with liquid BrF3 under Freon‐113 leads to the formation of Ba(BrF4)2 as a colorless microcrystalline powder. Here, we discuss its formation kinetics and thermodynamics. The compound crystallizes in the tetragonal space group I$\bar {4}$ with a = 9.65081(11) Å, c = 8.03453(13) Å, V = 748.32(2) Å3, and Z = 4 at 27 °C, and it is isotypic to Ba(AuF4)2. The structure contains square planar BrF4– anions. The compound is stable at ambient conditions excluding moisture and at temperatures up to approximately 200 °C. Solid‐state computational calculations of the Raman and IR spectra are in good agreement with the experimentally obtained ones, and in combination with its powder X‐ray diffraction pattern, density measurement, thermodynamics, elemental and EDXRF analyses, this shows that the compound is pure.

“…To determine the quantitative composition of obtained product of BaF 2 and BrF 3 interaction, the compound was hydrolyzed with diluted ammonia solution to dissolve it completely 5 . Barium has been determined gravimetrically as barium sulphate, bromine has been determined by the potentiometric titration with silver nitrate using eosin as an indicator and fluorine has been determined by the volumetric titration with zirconyl nitrate in the presence of sodium alizarin-sulfonate.…”

“…Products of interaction of BrF 3 and alkali metals fluorides are well known, but there is not enough data regarding such compounds of BrF 3 and alkali-earth metals fluorides. It is only known that it is possible to synthesize Ba (BrF 4 ) 2 using barium chloride and bromine (III) trifluoride 5 . It is also known that Ba (BrF 4 ) 2 is the only stable compound for all alkali-earth metals in this case 6 .…”

The barium fluorobromate (III) has been obtained as the product of interaction between barium fluoride and bromine (III) trifluoride. The heat of formation of Ba (BrF 4 ) 2 has been found by the isothermal calorimetry method. By the TG/DT analysis the thermal stability of Ba(BrF 4 ) 2 has been researched. It has been found that this compound was mostly stable in the atmosphere or argon up to 250°C.

“…These definitions can be applied to all protonic solvents, since proton transfer reactions are considered as responsible for both the auto-ionisation of the amphoteric solvent molecules and the acid-base interactions in their solutions In order to extend this concept to nonprotonic solutions, the concept of ionotropism has been proposed [11]. For example, the self-ionisation of liquid bromine trifluoride and the acid-base interactions in this solvent [12] were explained by fluoride ion transfer reactions and an acid defined as a fluoride ion donor and a base as a fluoride ion acceptor respectively.…”
