hyponitrite(2-) ion
Sign in to saveAlso known as [N2O2](2-), [ON=NO](2-)
In chemistry, hyponitrite may refer to the anion ([ON=NO]2−), or to any ionic compound that contains it. In organic chemistry, it may also refer to the group −O−N=N−O−, or any organic compound with the generic formula R1−O−N=N−O−R2, where R1 and R2 are organic groups. Such compounds can be viewed as salts and esters of hyponitrous acid. An acid hyponitrite is an ionic compound with the anion ([HON=NO]−).
