Phosphorus pentafluoride was first prepared in 1876 by the fluorination of phosphorus pentachloride using arsenic trifluoride, which remains a favored method: 3 PCl5 + 5 AsF3 → 3 PF5 + 5 AsCl3 Phosphorus pentafluoride can be prepared by direct combination of phosphorus and fluorine: P4 + 10 F2 → 4 PF5 See more Phosphorus pentafluoride, PF5, is a phosphorus halide. It is a colourless, toxic gas that fumes in air. See more Single-crystal X-ray studies indicate that the PF5 has trigonal bipyramidal geometry. Thus it has two distinct types of P−F bonds (axial and … See more Phosphorus pentafluoride is a Lewis acid. This property is relevant to its ready hydrolysis. A well studied adduct is PF5 with pyridine. With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula … See more WebBasis for revised IDLH: The revised IDLH for phosphorus pentachloride is 70 mg/m 3 based on acute inhalation toxicity data in animals [Henderson and Haggard 1943]. This may be a conservative value due to the lack of relevant acute toxicity data for workers.
