are named by adding the suffix "-diazonium" to the name of the parent substance RH, the whole being
followed by the name of the ion 
.
Examples to Rule C-931.1
Benzenediazonium chloride
8-Hydroxy-2-naphthalenediazonium tetrafluoroborate
931.2 - Compounds RN=NX are named by adding, after the name of the parent compound RH, the syllables "diazo" joined to the designation of the atom or group X.
Note: These compounds are distinguished from azo compounds by the fact that the group X is not joined to the nitrogen atom by a link from a carbon atom (except for the cyanide).
931.3 - Compounds RN=N-OM, where M is a metal, are named metal diazoates.Examples to Rule C-931.2
Benzenediazohydroxide
Benzenediazocyanide
Sodium benzenediazosulfonate
931.4 - Compounds containing a group N2 attached by one atom to carbon are named by adding a prefix "diazo-" for this substituent to the name of the parent compound.Example to Rule C-931.3
Sodium benzenediazoate
931.5 - Compounds in which a group -N=N- forms part of a ring are named as (a) cyclic compounds (see Section B) or (b), if the group creates a spiro ring system, by use of the prefix "-azi".Examples to Rule C-931.4
Diazomethane
Ethyl diazoacetate
-Diazoacetophenone
See Recommendations'93 R-5.3.3.3Examples to Rule C-931.5
(a) Ethyl 3H-diazirine-3-carboxylate
(b) 3-Azi-5b-androstan-17-one
