Compounds formally derived from the attachment of an amine $\ce{R3N}$ to a nitrene $\ce{RN{:}}$ . The structure $\ce{R3N^{+}–N−R}$ expresses the 1,2-dipolar character of amine imides. They may be named systematically as substituted diazan-2-ium-1-ides, e.g. $\ce{Me3N^{+}–N−Me}$, 1,2,2,2-tetramethyldiazan-2-ium-1-ide or trimethylamine $N$-methylimide.
