Inorganic imide

The inorganic imides are compounds containing an ion composed of nitrogen bonded to hydrogen with formula HN²⁻. Organic imides have the NH group, and two single or one double covalent bond to other atoms. The imides are related to the inorganic amides (H₂N⁻), the nitrides (N³⁻) and the nitridohydrides (N³⁻•H⁻).

In addition to solid state imides, molecular imides are also known in dilute gases, where their spectrum can be studied.

When covalently bound to a metal, an imide ligand produces a transition metal imido complex.

When the hydrogen of the imide group is substituted by an organic group, an organoimide results. Complexes of actinide and rare earth elements with organoimides are known.
