II-4.6 ORGANIC DERIVATIVES OF THE NITROGEN HYDRIDE LIGANDS

Organic derivatives are named as substitution products of the parents which have been named
as described in Section II-4.1 to Section II-4.5. When the compound contains two contiguous
nitrogen atoms they are designated by N1 and N2. In ligands where both nitrogen atoms carry
no formal charge or when the nitrogen atoms carry equal formal charges, the number 1 is
assigned to the nitrogen atom carrying most substituents. When each nitrogen atom has the
same number of substituents, that with the substituent of lower alphabetical order is num-
bered 1. The metal atom does not count as a substituent for these purposes. In ligands which
contain formally negatively charged nitrogen (see Section II-4.5), as well as neutral or posi-
tively charged nitrogen, the anionic nitrogen is designated by the number 1. If both nitrogen
atoms carry formal negative charges, that carrying the greater negative charge has priority for
number 1 (for more complex substitutions, see Chapters C-8 and C-9 of Note 4c).
