Nitrogen difluoride, also known as difluoroamino, is a reactive radical molecule with formula NF2. This small molecule is in equilibrium with its dimer tetrafluorohydrazine.[2]

N2F4 ⇌ 2 NF2

As the temperature increases the proportion of NF2 increases.[3]

The molecule is unusual in that it has an odd number of electrons, yet is stable enough to study experimentally.[4]
