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).
Tungsten(VI) oxytetrafluoride can be synthesized by the reaction of fluorine and tungsten trioxide. [4] It can also be obtained by treating tungsten with a mixture of oxygen and fluorine at high temperatures. [1] Partial hydrolysis of tungsten hexafluoride will also produce WOF 4. [9] WF 6 + H 2 O → WOF 4 + 2 HF

Oxygen's highest fluoride is oxygen difluoride, [89] but fluorine can theoretically (as of 2012) oxidize it to a uniquely high oxidation state of +4 in the fluorocation: OF + 3. [90] In addition, several chalcogen fluorides occur which have more than one chalcogen (O 2 F 2, [91] S 2 F 10, [92] etc.).
Tungsten tetrafluoride is an inorganic compound with the formula WF 4. This little studied solid has been invoked, together with tungsten pentafluoride , as an intermediate in the chemical vapor deposition of tungsten films using tungsten hexafluoride .
Oxygen forms heteropoly acids and polyoxometalate ions with tungsten, molybdenum and some other transition metals, such as phosphotungstic acid (H 3 PW 12 O 40) and octadecamolybdophosphoric acid (H 6 P 2 Mo 18 O 62). Oxygen can form oxides with heavier noble gases xenon and radon, although this needs indirect methods.
Hexafluoride-forming elements Octahedral structure of SF 6. Seventeen elements are known to form binary hexafluorides. [2] Nine of these elements are transition metals, three are actinides, four are chalcogens, and one is a noble gas.
Tungsten(V) fluoride is an inorganic compound with the formula WF 5. It is a hygroscopic yellow solid. It is a hygroscopic yellow solid. Like most pentafluorides, it adopts a tetrameric structure, consisting of [WF 5 ] 4 molecules.
