- Diacyl derivatives of ammonia or primary @A00274@, especially those cyclic compounds derived from diacids, e.g. I02948.png
- In @A00134@ 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 @A00512@ of an RN= group to N, P, O, S, Se, Te. E.g. @A00271@, @A00562@.
- Salts having the @A00358@ RN2−.
