Table III Continued

inous Ending of the parent names of acids of the types H 2 X(OH) (X ¼ N, P, As, Sb),
e.g. stibinous acid. See Table IR-8.1 for other such names.
inoyl Ending of prefixes for substituent groups formed by removing all hydroxy groups from
‘inic’ acids (see above), e.g. phosphinoyl, H 2 P(O) ; s eleninoyl, HSe(O) . ( See Table IR-
8.1 for phosphinic and seleninic acids.)
inyl Ending of prefixes for the divalent substituent groups 4X¼O ( sulfinyl, seleninyl and
tellurinyl for X ¼ S, Se and Te, respectively).

io Ending of acceptable alternative prefixes for certain cationic substituent groups, e.g.
ammonio for azaniumyl, pyridinio for pyridiniumyl (cf. Section IR-6.4.9).
Now abandoned ending of prefixes for substituent groups consisting of a s ingle atom,
e.g. mercurio, Hg .
irane General ending of parent names of three-membered saturated heteromonocycles in
Hantzsch–Widman nomenclature, cf. S ection IR-6.2.4.3. See also ‘iridine’.
irene General ending of parent names of three-membered heteromonocycles with the maximum
number of non-cumulative double bonds (i.e. one double bond) in Hantzsch–Widman
nomenclature, cf. S ection IR-6.2.4.3. See also ‘irine’.
iridine Ending of parent names of three-membered nitrogen-containing saturated
heteromonocycles in Hantzsch–Widman nomenclature, cf. S ection IR-6.2.4.3.
irine Ending of parent names of three-membered heteromonocycles with the maximum number
of non-cumulative double bonds (i.e. one double bond) and N a s t he only heteroatom(s) in
Hantzsch–Widman nomenclature, cf. S ection IR-6.2.4.3.
ite Ending of names of anions and esters of oxoacids having the ‘ous’ or the ‘orous’ ending in
the acid name, e.g. hypochlorite (from hypochlorous acid), methyl sulfite (from sulfurous
acid). Cf. Table IR-8.1. See also ‘inite’, ‘onite’.
ito Ending of name of any anion with an ‘ite’ name (see above) acting as a l igand, e.g. nitrito,
sulfito. Cf. S ections IR-7.1.3 and IR-9.2.2.3 and Table IX. See also ‘inito’, ‘onito’.

ium Ending of names of many elements and their cations, e.g. helium, seaborgium,
thallium(1þ), and of the name of any new element (cf. R ef. 1 o f C hapter IR-3).
Suffix to indicate addition of hydrons to a p arent hydride or other parent structure (see
‘anium’, ‘enium’, ‘inium’, ‘onium’, ‘ynium’), accompanied by multiplying prefixes and
þ
þ
þ
locants as appropriate, e.g. hydrazinium, H 2 NNH 3 ; h ydrazine-1,2-diium, H 3 NNH 3 .
o T erminal vowel indicating a n egatively charged ligand; see ‘ato’, ‘ido’, ‘ito’.
Terminal vowel of prefixes for many inorganic and organic substituent groups, e.g. amino,
chloro, oxido, sulfo, thiolato.
Terminal vowel of prefixes for fusion components. (See Section P-25.3 of the Blue
b
Book .) See also ‘eno’, ‘ino’.
Terminal vowel of infixes used in functional replacement nomenclature (Section IR-8.6)
to indicate replacement of oxygen atoms and/or hydroxy groups, e.g. ‘amido’, ‘nitrido’,
‘thio’.
ocane Ending of parent names of eight-membered saturated heteromonocycles in Hantzsch–
Widman nomenclature, cf. S ection IR-6.2.4.3.
ocene Ending of the names of certain bis(cyclopentadienyl)metal compounds, e.g. ferrocene. Cf.
Section IR-10.2.6.
