Lithium hyponitrite is a compound that is not stable and does not exist in a readily isolable form. Therefore, there is no known or commonly accepted chemical formula for it.

Hyponitrite ion (N₂O₂²⁻) itself is quite unstable and readily decomposes in solution, making it difficult to form salts with it.

It's important to remember that just because we can write a formula doesn't mean the compound is stable or readily exists.
