Also known as NO(+), [NO](+), oxidonitrogen(+), nitrilooxonium, nitric oxide(1+), nitrogen oxide cation, nitrosyl ion, nitrosyl

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 .
