Abstract

A new synthesis of bis (triphenyl-λ 5-phosphanylidene) ammonium fluoride ((Ph 3 PNPPh 3) F, abbreviated as (PNP) F), is described. The title compound has been fully characterized by multinuclear NMR spectroscopy, vibrational spectroscopy, elemental analysis and single crystal and powder X-ray diffraction for the first time. In the solid state (PNP) F exists as a covalent molecular compound, in which the fluoride ion is asymmetrically bonded to the ...
