According to NMR spectroscopy and X\u2010ray crystallography, <jats:bold>1<\/jats:bold> is monomeric both in solution and in the solid state. The intramolecular P<jats:bold>\u22c5\u22c5\u22c5<\/jats:bold>B distance of 2.900(5)\u2005\u00c5 and the full planarity of the borane site exclude any significant P\/B interaction.
