Delocalized anion systems are treated in the same manner as their
cationic counterparts: naming either refers in detail to the weightiest
and/or most plausible resonance structure or reflects only summarily all
functions in question, but without locants.

by no means always, under the name of the respective parent system and
in the rather descriptive format ... ion(x-).
