In additive nomenclature, in which imide is analogous to oxide, the term is used to name compounds of the type R3Y+–N−R (Y = N, P) and R2Z+–N−R (Z = O, S, Se, Te), which are the products of formal attachment of an RN= group to N, P, O, S, Se, Te. E.g. amine imides, azomethine imides.
Salts having the anion RN2−.
