Salts RN=NO−M+ (R commonly @A00464@) of the compounds RN=NOH , (hydrocarbon)diazohydroxides, e.g. PhN=NO−K+ potassium benzenediazoate. In the IUPAC 'Blue Book' these compounds are named as hydrocarbyldiazenolates and hydrocarbyldiazenols, respectively. E.g. PhN=NOH phenyldiazenol. RN=NO−M+ are also known by the non-IUPAC name diazotates.
