Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula W F 6. It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m 3 (22 lb/cu yd) (roughly 11 times heavier than air). [2] [3] It is the densest known gas under standard ambient temperature and pressure (298 K, 1 atm). [4]
Pentafluoroethyl iodide can be produced by electrochemical fluorination of 1,1,2,2-tetrafluoro-1,2-diiodoethane. [3] 2 C 2 F 4 I 2 + 2 HF → C 2 F 5 I + I 2 + H 2. It can also be produced by react tetrafluoroethylene, iodine and iodine pentafluoride. [4] 5 C 2 F 4 + 2 I 2 + IF 5 → 5 C 2 F 5 I

The reaction of tungsten(VI) oxytetrachloride and hydrogen fluoride will also produce WOF 4. [3] WOCl 4 + 4HF → WOF 4 + 4HCl. WOF 4 can also prepared by the reaction of lead(II) fluoride and tungsten trioxide at 700 °C. [3] 2PbF 2 + WO 3 → WOF 4 + 2PbO. Tungsten(VI) oxytetrafluoride hydrolyzes into tungstic acid.
