Laboratory routes to the solvent-free materials are numerous. A well documented route involves the thermal decomposition of diazonium salts of [BF 4] −: [11] [PhN 2] + [BF 4] − → PhF + BF 3 + N 2. It forms by treatment of a mixture boron trioxide and sodium tetrafluoroborate with sulfuric acid: [12] 6 Na[BF 4] + B 2 O 3 + 6 H 2 SO 4 → 8 ...
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.
Pure H[BF 4] has not been described. The same holds true for the superacids that are known by the simplified formulas H[PF 6] and H[SbF 6]. [4] [5] However, a solution of BF 3 in HF is highly acidic, having an approximate speciation of [H 2 F] + [BF 4] − (fluoronium tetrafluoroborate) and a Hammett acidity function of −16.6 at 7 mol % BF 3, easily qualifying as a superacid.
