The reaction of KPO2F2 with the strong Lewis acid SbF5 was studied as a potential pathway to the unknown PO2+ cation. The resulting product has the desired PO2SbF6 composition but consists of an eight-membered, antimony-oxygen-phosphorus-bridged ring that was characterized by vibrational and NMR spectroscopy, ab initio methods, and a single crystal x-ray diffraction study. The preferred formation of the ring and its mechanism are discussed. Wiley-VCH Verlag GmbH, 2001.

The preparations of the salts PH3F+SbF6- and PHF3+Sb2F11- are reported.All fluorophosphonium cations PH4-nFn+ are characterized by multinuclear (1H, 19F, 31P) NMR spectroscopy.For n > 1 these salts are easily accessible by fluoride abstraction from fluorohydridophosphates(V).PH3F+SbF6-, however, is obtained in the reaction of PH3F2 with SbF5. - keywords: Fluorophosphonium Salts, Formation, NMR Spectra
