Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
The nitrosoniumion is NO, 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: NOClO4, NOSO4H (nitrosylsulfuric acid, more descriptively written NOSO3OH) and NOBF4. The ClO−4 and BF−4 salts are slightly soluble in acetonitrileCH3CN. NOBF4 can be purified by sublimation at 200–250 °C and 0.01 mmHg (1.3 Pa).
