Oxycations

chemical species containing a positively-charged oxygen with 3 bonds

The nitrosonium ion is , in which the nitrogen atom is bonded to an oxygen atom with a bond order of 3, and the overall diatomic species is cationic, bearing a positive charge. It can be viewed as nitric oxide with one electron removed. This ion is usually obtained as the following salts: , (nitrosylsulfuric acid, more descriptively written ) and . The perchlorate| and tetrafluoroborate| salts are slightly soluble in acetonitrile . NOBF4 can be purified by sublimation at 200–250 °C and .

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.

In chemistry, chloryl refers to a triatomic cation with chemical formula . This species has the same general structure as chlorite () but it is electronically different, with chlorine having a +5 oxidation state (rather than the +3 of chlorite). This makes it a rare example of a positively charged oxychloride. Chloryl compounds, such as Chloryl fluoride| and [ClO2][RuF6], are all highly reactive and react violently with water and most organic compounds.

Rosocyanine and rubrocurcumin are two red colored materials, which are formed by the reaction between curcumin and borates.

An oxycation, or oxocation, is an ion with the generic formula (where A represents a chemical element and O represents an oxygen atom). Their names normally end with the suffix "-ium" or "-yl".

Pervanadyl is jargon that has two meanings. Pervanadyl can refer to aquo complexes containing (). This pale yellow oxycation of vanadium(V) is the predominant vanadium(V) species in acidic solutions with pH between 0 and 2. Like permanganate, pervanadate features the metal in its highest oxidation state.
