2-Vinyl­pyridine-tris­(penta­fluoro­phen­yl)borane hexane monosolvate

The title compound, C₇H₇N·B(C₆F₅)₃·C₆H₁₄, was obtained by the stoichiometric reaction of 2-vinyl­pyridine and tris­(penta­fluoro­phen­yl)borane in toluene. The formed adduct exhibits a restricted rotation along the B-N bond resulting in an asymmetry, which can be also observed in the ¹⁹F NMR spectra. The B-N distance is equivalent to the distances found for 2-methyl­pyridine and 2-ethyl­pyridine B(C₆F₅)₃ adducts. For the final refinement, the contributions of disordered solvent mol­ecules were removed from the diffraction data with SQUEEZE in PLATON [van der Sluis & Spek (1990). Acta Cryst. A46, 194-201; Spek (2009). Acta Cryst. D65, 148-155].

Tri-tert-butyl­phospho­nium hy­droxy­tris­(penta­fluoro­phen­yl)borate

The ionic title compound, C₁₂H₂₈P⁺·C₁₈HBF₁₅O⁻, was obtained by the stoichiometric reaction of ^tBu₃P, B(C₆F₅)₃ and water in toluene. A weak P—H...O hydrogen bond is observed in the crystal structure.
