What is the structure of (O2F2) oxygen fluoride

The compound id produced as result of glow dischage through amixture of O₂ and F₂ at -180 to -190 degree (c). As should be expected. O₂F₂ is an extremely reactive fluorinating agent. Under the conditions that produce OF₂, small and O₄F₂ are produced, but these unstable compounds decomposed at liquid nitrogen temperatures.

Why Bond length of O-O is greater in H₂O₂ than O₂F₂?

Electronegativity of F is much more than hydrogen and also hybridization of oxygen atoms in of H₂O₂ and O₂F₂ both have (sp3) same and hence we can apply bent’s rule.

According bent’s rule more eletronegative atoms reduce % s-character (or increases % p-character vice versa) of those hybride orbital in which they attach. So in case of O₂F₂ % s-character of those hybride orbital decrease which have  flourine while % p-character increases in same way % s-character of  remaing hybride orbital inceases and p-character decreases hence its bond length also (bond length is directly proportional to % p-character) decreases.  hence O-O bond length in O₂F₂ is shorter thane H₂O₂.
