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