Chlorine pentafluoride is an interhalogen compound with formula ClF 5. This colourless gas is a strong oxidant that was once a candidate oxidizer for rockets. The molecule adopts a square pyramidal structure with C 4v symmetry, [1] as confirmed by its high-resolution 19 F NMR spectrum. [2] It was first synthesized in 1963. [3]
Fluorine forms a great variety of chemical compounds, within which it always adopts an oxidation state of −1. With other atoms, fluorine forms either polar covalent bonds or ionic bonds. Most frequently, covalent bonds involving fluorine atoms are single bonds, although at least two examples of a higher order bond exist. [2]

[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
Structure of xenon oxytetrafluoride, an example of a molecule with the square pyramidal coordination geometry. Square pyramidal geometry describes the shape of certain chemical compounds with the formula ML 5 where L is a ligand. If the ligand atoms were connected, the resulting shape would be that of a pyramid with a square base.
On the other hand, some compounds that are normally written with ionic bonds in order to conform to the octet rule, such as ozone O 3, nitrous oxide NNO, and trimethylamine N-oxide (CH 3) 3 NO, are found to be genuinely hypervalent. Examples of γ calculations for phosphate PO 3− 4 (γ(P) = 2.6, non-hypervalent) and orthonitrate NO 3−
Phosphorus pentafluoride is a relatively inert gas, notable as a mild Lewis acid and a fluoride ion acceptor. It is a fluxional molecule in which the axial (ax) and equatorial (eq) fluorine atoms interchange positions by the Berry pseudorotation mechanism .
ClO 2 F was first reported by Schmitz and Schumacher in 1942, who prepared it by the fluorination of ClO 2. [2] The compound is more conveniently prepared by reaction of sodium chlorate and chlorine trifluoride [3] and purified by vacuum fractionation, i.e. selectively condensing this species separately from other products.
