  1. Diacyl derivatives of ammonia or primary amines, especially those cyclic compounds derived from diacids, e.g.

  2. 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.
  3. Salts having the anion RN2−.
