Other Polynitrogen Parent Systems
Trivial names of freely substitutable polynitrogen parent structures as
recommended for further use by IUPAC and the most important substituent groups derived therefrom are compiled in Table 13. Differing
names and numberings as employed by Chern. Abstr. are enclosed in
parentheses.
