Salts RN=NO⁻M⁺ (R commonly aryl) 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.
