A number of novel tetra-arylfluorophosphoranes have been synthesised.The most stable form of these compounds is the ionic form PR4+F- (R=aryl) although various other forms have been shown to exist including a molecular monomer PR4F and a dimer PR4+PR4F2-.The i.r. spectra of the ionic forms reveal strong P+...F- interactions.The fluorides are prepared via the hydrogendifluorides PR4+HF2- which contain distorted HF2- ions.
