Selenium hexafluoride is the inorganic compound with the formula SeF 6. It is a very toxic colourless gas described as having a "repulsive" odor. [ 5 ] It is not widely encountered and has no commercial applications.
In comparison with its sulfur counterpart (sulfur hexafluoride), selenium hexafluoride (SeF 6) is more reactive and is a toxic pulmonary irritant. [28] Selenium tetrafluoride is a laboratory-scale fluorinating agent.
Selenium dichloride is an important reagent in the preparation of selenium compounds (e.g. the preparation of Se 7). It is prepared by treating selenium with sulfuryl chloride (SO 2 Cl 2 ). [ 10 ] Selenium reacts with fluorine to form selenium hexafluoride :

Pentafluoroselenium hypofluorite can also formed from selenium oxyfluoride and fluorine gas in the presence of potassium fluoride. [4] [5] SeOF 2 + KF → K + [SeOF 3] − — F 2 → K + [SeOF 5] − — F 2 → KF + SeOF 6. The reaction of fluorine gas and Hg(OSeF 5) 2 produces SeOF 6 in much higher yield and with less SeF 6. [3]
A hexafluoride is a chemical compound with the general formula QX n F 6, QX n F 6 m−, or QX n F 6 m+. Many molecules fit this formula. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6 ), which is a byproduct of the mining of phosphate rock .
Selenium tetrafluoride (Se F 4) is an inorganic compound.It is a colourless liquid that reacts readily with water. It can be used as a fluorinating reagent in organic syntheses (fluorination of alcohols, carboxylic acids or carbonyl compounds) and has advantages over sulfur tetrafluoride in that milder conditions can be employed and it is a liquid rather than a gas.
A hexafluoride is a chemical compound consisting of one central atom surrounded by six fluorine atoms. Wikimedia Commons has media related to Hexafluorides . Pages in category "Hexafluorides"
