Phosphorus pentafluoride is a colorless gas that fumes strongly in air. Phosphorus pentafluoride has a boiling point of -84.6C and has high thermal stability. Dry Phosphorus pentafluoride does not attack glass even at 250c, but a trace of moisture leads to formation of POF and HF( which does attack glass).
