Nitrogen difluoride, also known as difluoroamino, is a reactive radical molecule with formula N F₂. This small molecule is in equilibrium with its dimer tetrafluorohydrazine.

N₂F₄ ⇌ 2 NF₂

As the temperature increases the proportion of NF₂ increases.

The molecule is unusual in that it has an odd number of electrons, yet is stable enough to study experimentally.
