Organophosphoryl adducts of tris(pentafluorophenyl)borane; crystal and molecular structure of B(C6F5)3·Ph3Po

Article abstract of DOI:10.1039/b100981h

The synthesis and characterisation of a series of phosphoryl donor complexes of B(C₆F₅)₃ were reported and their spectroscopic properties were investigated. The changes in the ³¹P NMR chemical shifts and the phosphoryl stretching frequencies arising from coordination of the phosphoryl ligand to B(C₆F₅)₃ were described. B(C₆F₅)₃ was further characterised in the solid state by a single-crystal X-ray diffraction study. The X-ray diffraction study displayed weak intramolecular π-stacking interactions between the eclipsed interlocking C₆F₅ and C₆H₅ rings.
