- @C00907@ (with their @C01371@) derived by addition of a @H02904@ to a mononuclear @P04405@ of the nitrogen, chalcogen and halogen families.
(H4N+) ammonium
(H3O+) oxonium
(H2F+) fluoronium
(H4P+) phosphonium
(H3S+) sulfonium
(H2Cl+) chloronium
(H4As+) arsonium
(H3Se+) selenonium
(H2Br+) bromonium
(H4Sb+) stibonium
(H3Te+) telluronium
(H2I+) iodonium
(H4Bi+) bismuthonium - Derivatives formed by substitution of the above parent ions by univalent groups. The number of substituted hydrogen atoms is, especially in the case of @H02891@ substituents, indicated by the adjectives primary, secondary, tertiary or quaternary. E.g. (Cl2F+) dichlorofluoronium, (CH3)2S+H dimethylsulfonium (a secondary sulfonium ion), Cl(CH3)3P+ chlorotrimethylphosphonium, (CH3CH2)4N+ tetraethylammonium (a quaternary ammonium ion).See also:arsonium compounds,halonium ions,oxonium ions,phosphonium compounds,quaternary ammonium compounds,stibonium compounds,sulfonium compounds
- Derivatives formed by substitution of the above parent ions by groups having two or three free valencies on the same atom. Such derivatives are, where possible, designated by a specific class name. E.g. RC≡O+ hydrocarbylidyne @O04378@, R2C=N+H2X−@I02958@, RC≡NH+@N04156@.
