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 ...
The covalent radius of fluorine of about 71 picometers found in F 2 molecules is significantly larger than that in other compounds because of this weak bonding between the two fluorine atoms. [9] This is a result of the relatively large electron and internuclear repulsions, combined with a relatively small overlap of bonding orbitals arising ...
Krypton compounds with other than Kr–F bonds (compounds with atoms other than fluorine) have also been described. KrF 2 reacts with B(OTeF 5) 3 to produce the unstable compound, Kr(OTeF 5) 2, with a krypton-oxygen bond.
Krypton(IV) fluoride is a hypothetical inorganic chemical compound of krypton and fluorine with the chemical formula KrF 4. At one time researchers thought they had synthesized it, but the claim was discredited. [1] The compound is predicted to be difficult to make and unstable if made. [2]

Calcium difluoride is a notable compound. In the form of the mineral fluorite it is the major source of commercial fluorine. It also has an eponymic crystal structure, which is an end member of the spectrum starting from bixbyite and progressing through pyrochlore .
A krypton-nitrogen bond is found in the cation [HC≡N–Kr–F] +, produced by the reaction of KrF 2 with [HC≡NH] + [AsF − 6] below −50 °C. [35] [36] HKrCN and HKrC≡CH (krypton hydride-cyanide and hydrokryptoacetylene) were reported to be stable up to 40 K. [27] Krypton hydride (Kr(H 2) 4) crystals can be grown at pressures above 5 ...
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.
