In chemistry, hyponitrite may refer to the anion N
2O2−
2 or [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, respectively, of hyponitrous acid H
2N
2O
2 or HON=NOH.
An acid hyponitrite is an ionic compound with the anion HN
2O−
2 or [HON=NO]−
There are cis and trans forms of the hyponitrite ion.
The trans form is generally found in hyponitrite salts such as sodium hyponitrite, Na
2N
2O
2 and silver(I) hyponitrite, Ag
