dioxygenyl ion
Sign in to saveAlso known as dioxygenyl
The dioxygenyl ion, , has been studied in both the gas phase and in salts with anions that cannot be oxidized. The first synthesis was []. Rather than the double bond of , the bond order is considered to be . Relative to most molecules, this ionization energy is very high at 1175 kJ/mol. As a result, the scope of the chemistry of is quite limited, acting mainly as a 1-electron oxidiser.

==Structure and molecular properties== has a bond order of 2.5, and a bond length of 112.3 pm in solid O2[AsF6]. It is isoelectronic with nitric oxide and is paramagnetic. The bond energy is 625.1 kJ mol−1 and the stretching frequency is 1858 cm−1, both of which are high relative to most of the molecules.
