Radicals cations,
R3N·+
, derivable from aminium ions,
R3NH+
, by removal of a hydrogen atom. Aminiumyl radical ions are, except for
H3N·+
, synonymous with the ammoniumyl radical ions. As the term ammonium is well known, ammoniumyl radical ions is the more desirable class name.
See: ammoniumyl radical ions
