Tetrafluoroborate

It arises by the reaction of fluoride salts with the Lewis acid BF 3 , treatment of tetrafluoroboric acid with base, or by treatment of boric acid with hydrofluoric acid. Safety considerations, however, overshadow this inconvenience. With a formula weight of Moreover, in other cases of ostensibly "cationic" complexes, the fluorine atom in fact acts as a bridging ligand between boron and the cationic center. Transition and heavy metal fluoroborates are produced in the same manner as other fluoroborate salts; the respective metal salts are added to reacted boric and hydrofluoric acids. Tin , lead , copper , and nickel fluoroborates are prepared through electrolysis of these metals in a solution containing HBF 4. Potassium fluoroborate is obtained by treating potassium carbonate with boric acid and hydrofluoric acid. Fluoroborates of alkali metals and ammonium ions crystallize as water-soluble hydrates with the exception of potassium , rubidium , and cesium. Imidazolium and formamidinium salts, ionic liquids and precursors to stable carbenes , are often isolated as tetrafluoroborates. Contents move to sidebar hide. Article Talk. Read Edit View history.

Tetrafluoroborate

Unlike other strong acids like H 2 SO 4 or HClO 4 , the pure solvent free tetrafluoroboric acid more precisely, pure hydrogen tetrafluoroborate H[BF 4 ] does not exist. The term "fluoroboric acid" refers to a range of chemical compounds, depending on the solvent. The solvent can be any suitable Lewis base. It is mainly produced as a precursor to other fluoroborate salts. Fluoroboric acid is corrosive and attacks the skin. It is available commercially as a solution in water and other solvents such as diethyl ether. It is a strong acid with a weakly coordinating , non-oxidizing conjugate base. Pure H[BF 4 ] has been described as a "nonexistent compound", as a sufficiently "naked" proton is expected to abstract a fluoride from the tetrafluoroborate ion to give hydrogen fluoride and boron trifluoride :. These salts consist of protonated solvent as a cation, e. The anion and cations are strongly hydrogen-bonded.
