Although selenium hexafluoride is quite inert and slow to hydrolyze, it is toxic even at low concentrations, [9] especially by longer exposure. In the U.S., OSHA and ACGIH standards for selenium hexafluoride exposure is an upper limit of 0.05 ppm in air averaged over an eight-hour work shift.
SeF 6, SeO 3: Except where otherwise noted, ... Structure. The shape of the molecule is a distorted tetrahedron with the O-Se-O angle being 126.2°, ...
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
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.
The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...
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.

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.
