Term: aminium ions
https://doi.org/10.1351/goldbook.A00277

Definition:
Cations HR3N+ formed by hydronation of an amine R3N. 'Non-quaternary ammonium ions' is a synonymous term, e.g. prolinium, PhN+HMe2, N,N-dimethylanilinium.


Note: If a class X can be hydronated to Xium ions the class Xium ions commonly includes the derivatives formed by the replacement of the added @H02904@ with a hydrocarbyl group. Aminium ions form an exception, made possible by the availability of the class name ammonium ions.
