Monoisotopic mass 125.965775 Da. Fumes strongly in air, with traces of moisture forming POF3 and HF (corrosive). This section provides a listing of alternate names for this chemical, With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula [PF 4 (NR 2)] 2. ... PHOSPHORUS PENTAFLUORIDE, ADSORBED . National Ocean Service, Warning: Phosphorus pentachloride is a corrosive agent. With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula [PF4(NR2)]2. The apparent equivalency arises from the low barrier for pseudorotation via the Berry mechanism, by which the axial and equatorial fluorine atoms rapidly exchange positions. A variety of complexes are known with bidentate ligands.[4]. A well studied adduct is PF5 with pyridine.
