Table III Suffixes and endings a

a T erminal vowel of prefixes indicating replacement of:
carbon atoms by atoms of other elements in skeletal replacement nomenclature (Section
IR-6.2.4.1) and Hantzsch–Widman nomenclature (Section IR-6.2.4.3), e.g. ‘oxa’, ‘aza’;
boron atoms by atoms of other elements in boron hydride-based nomenclature (Section
IR-6.2.4.4), e.g. ‘carba’, ‘thia’;
heteroatoms by carbon atoms in natural product nomenclature (prefix ‘carba’).
See Table X f or ‘a’ prefixes for all elements.
ane Ending of names of neutral saturated parent hydrides of elements of Groups 13–17,
4
e.g. thallane, cubane, cyclohexane, cyclohexasilane, diphosphane, tellane, l -tellane. Cf.
Section IR-6.2.2 and Table IR-6.1.
Last part of endings of a n umber of parent names of saturated heteromonocycles
in Hantzsch–Widman nomenclature, i.e. of ‘irane’, ‘etane’, ‘olane’, ‘ane’, ‘inane’, ‘epane’,
‘ocane’, ‘onane’ and ‘ecane’ (see Section IR-6.2.4.3).
anide Combined ending of names of anions resulting from the removal of a h ydron from a p arent

hydride with an ‘ane’ name, formed by adding the suffix ‘ide’, e.g. methanide, CH 3 .
Cf. S ection IR-6.4.4.
anium Combined ending of names of cations resulting from the addition of a h ydron to a p arent
þ
structure with an ‘ane’ name, formed by adding the suffix ‘ium’, e.g. phosphanium, PH 4 .
Cf. S ection IR-6.4.1.
ano Ending resulting from the change of the ‘ane’ ending in names of parent hydrides to form
prefixes denoting bridging divalent substituent groups, e.g. diazano, HNNH .
ate General ending of additive names of anions, e.g. tetrahydridoaluminate(1 ), [AlH 4 ] . C f.

Section IR-7.1.4 and Table X.
Ending of names of anions and esters of inorganic oxoacids having the ‘ic’ ending in the
acid name, e.g. nitrate, phosphonate, trimethyl phosphate, and of anions and esters of
organic acids, e.g. acetate, methyl acetate, thiocyanate. See Tables IR-8.1 and IR-8.2 and
Table IX for more examples of ‘ate’ anion names. See also ‘inate’, ‘onate’.

ato Ending of name of any anion with an ‘ate’ name (see above) acting as a l igand, e.g.
tetrahydridoaluminato(1 ), nitrato, acetato. Cf. S ections IR-7.1.3 and IR-9.2.2.3 and Table
IX. See also ‘inato’, ‘onato’.

Ending of prefixes for certain anionic substituent groups, e.g. carboxylato, C(¼O)O ;

phosphato, O P(¼O)(O ) 2 . S ee also ‘onato’.
diene See ‘ene’.
diide See ‘ide’.
diido See ‘ido’.
diium See ‘ium’.

diyl Combined suffix composed of the suffix ‘yl’ and the multiplicative prefix ‘di’, indicating
the loss of two hydrogen atoms from a p arent hydride resulting in a d iradical, or a
substituent group with two single bonds, if necessary accompanied by locants, e.g.
*
*
hydrazine-1,2-diyl, HNNH or HNNH ; p hosphanediyl, HP5. S ee also ‘ylidene’.
diylium See ‘ylium’.
ecane Ending of parent names of ten-membered saturated heteromonocycles in Hantzsch–
Widman nomenclature, cf. S ection IR-6.2.4.3.
