- Item2-Vinyl-pyridine-tris-(penta-fluoro-phen-yl)borane hexane monosolvate(Chester : International Union of Crystallography, 2012) Klahn, M.; Spannenberg, A.; Rosenthal, U.The title compound, C7H7N·B(C 6F5)3·C6H14, was obtained by the stoichiometric reaction of 2-vinyl-pyridine and tris-(penta-fluoro-phen-yl) 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-methyl-pyridine and 2-ethyl-pyridine B(C6F5)3 adducts. For the final refinement, the contributions of disordered solvent mol-ecules 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].
- ItemTri-tert-butylphosphonium hydroxytris-(pentafluorophenyl)borate(Chester : International Union of Crystallography, 2012) Klahn, M.; Spannenberg, A.; Rosenthal, U.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.
