Selenium hexafluoride (selenium(VI) fluoride), SeF 6 Index of chemical compounds with the same name This set index article lists chemical compounds articles associated with the same name.
Seleninyl fluoride can be produced by the reaction of selenium oxychloride and potassium fluoride. [3] 2 KF + SeOCl 2 → 2 KCl + SeOF 2. It can also be produced by the reaction of selenium tetrafluoride with water or selenium dioxide. [2] SeF 4 + H 2 O → SeOF 2 + 2 HF SeF 4 + SeO 2 → 2 SeOF 2
trineodymium fluoride tetraselenite Nd 3 (SeO 3) 4 F hexagonal P6 3 mc: a=10.515 c=7.1211 [23] trisamarium fluoride tetraselenite Sm 3 (SeO 3) 4 F hexagonal P6 3 mc: a=10.474 c=7.0224 [23] trigadolinium tetraselenite fluoride Gd 3 (SeO 3) 4 F 4:1 hexagonal P6 3 mc: a = 10.443 b = 6.9432 Z=2 [24] [1] tridysprosium tetraselenite fluoride Dy 3 ...
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]
Selenium compounds are compounds containing the element selenium (Se). Among these compounds, selenium has various oxidation states , the most common ones being −2, +4, and +6. Selenium compounds exist in nature in the form of various minerals, such as clausthalite , guanajuatite , tiemannite , crookesite etc., and can also coexist with ...
Selenoyl fluoride can be formed by the action of warm fluorosulfonic acid on barium selenate [5] or selenic acid. SeO 3 + SeF 4 can give this gas along with other oxyfluorides. Reactions

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.
