Krypton difluoride, KrF 2 is a chemical compound of krypton and fluorine. It was the first compound of krypton discovered. [2] It is a volatile, colourless solid at room temperature. The structure of the KrF 2 molecule is linear, with Kr−F distances of 188.9 pm. It reacts with strong Lewis acids to form salts of the KrF + and Kr 2 F + 3 ...
Krypton (from Ancient Greek: κρυπτός, romanized: kryptos 'the hidden one') is a chemical element; it has symbol Kr and atomic number 36. It is a colorless, odorless noble gas that occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps .
Difluorides are chemical compounds with two fluorine atoms per molecule (or per formula unit). Metal difluorides are all ionic. Despite being highly ionic, the alkaline earth metal difluorides generally have extremely high lattice stability and are thus insoluble in water. The exception is beryllium difluoride.
In chemistry, noble gas compounds ... whose formula was proposed to be Xe + ... synthesis of krypton difluoride (KrF 2) was reported in 1963. [11] True noble gas ...
Its lighter neighbor, krypton also forms well-characterized compounds, e.g., krypton difluoride. Krypton tetrafluoride was reported in 1963, [104] but was subsequently shown to be a mistaken identification; the compound seems to be very hard to synthesize now (although even the hexafluoride may exist).

Krypton hexafluoride is an inorganic chemical compound of krypton and fluorine with the chemical formula KrF 6. It is still a hypothetical compound . [ 1 ] Calculations indicate it is unstable.
The solid, crystalline difluoride XeF 2 is formed when a mixture of fluorine and xenon gases is exposed to ultraviolet light. [3] The ultraviolet component of ordinary daylight is sufficient. [4] Long-term heating of XeF 2 at high temperatures under an NiF 2 catalyst yields XeF 6. [5] Pyrolysis of XeF 6 in the presence of NaF yields high-purity ...
