A type of positively charged organic ion or cation that contains both azo and oxo (oxygen-containing) functional groups bonded together.
From azox- (azo + oxo, combining forms meaning nitrogen-to-nitrogen and oxygen-containing) + -onium (a suffix for positively charged ions). This specialized term emerged in 20th-century organic chemistry.
Azoxonium ions are exotic molecular species that only exist under specific conditions—creating and studying them helps chemists understand how complex organic molecules can rearrange and transform.
