Anions, inorganic nomenclature

This is an extremely complex field, requiring major modifications to organic nomenclature and the use of terms and techniqnes from inorganic nomenclature. Even so, there are a significant number of boron componnds whose names are not satisfactory to members of either the organic or inorganic community (see Fox and Powell, loc. cit.. Chapter 27, for details). Because the number of hydrogen atoms in neutral and anionic boron hydrides often bears no simple relationship to the number of boron atoms, borane names must express the number of both. 

General suffix for many polyatomic anions in inorganic nomenclature (including coordination nomenclature) and in organic nomenclature nitrate, acetate, hexacyanoferrate. 

See Secs. 3.1.2.2 and 3.1.2.8 for naming monatomic and certain polyatomic anions. When an organic group occurs in an inorganic compound, organic nomenclature (q.v.) is followed to name the organic part. 

The abbreviations for the investigation methods are also taken from the nomenclature of Sillen and Martel 1 (76) aiex = anion exchange cal = calorimetry ciex = cation exchange dis = distribution between two phases est = estimate red = e.m.f. with redox electrode sp = spectrophotometry. Our selected data, rather limited in number, arise from the present status of the IAEA assessment of inorganic complexes of the actinides (12). 

This system is additive and was developed originally to name coordination compounds, although it can be used in other circumstances when appropriate. For a discussion, see the Nomenclature of Inorganic Chemistry, Chapter 10. The compound to be named is considered as a central atom together with its ligands, and the name is developed by assembling the individual names of the constituents. This system has also been applied to name oxoacids and the related anions. Coordination names for oxoanions are cited in the examples throughout the text, and they are presented in detail in Section 4.4.5 (p. 69).

The chapter on Oxoacids and Derived Anions (Red Book I, Chapter 1-9) has also been extensively modified. Now called Inorganic Acids and Derivatives (Chapter IR-8), it includes the slightly revised concept of hydrogen names in Section IR-8.4 (and some traditional ous and ic names have been reinstated for consistency and because they are required for organic nomenclature purposes, i.e. in the new Blue Book). 

Inorganic chemists also use a further termination to indicate the name of a cation. This is the ending -ate, and it is used as a modification of the name of an oxoacid. Thus sulfuric acid, H2SO4, gives rise to sulfate, S04, phosphoric acid to phosphate, P04, and nitric acid to nitrate, NO3. The partially deprotonated anions such as HS04 and H2P04 are rather more comphcated to deal with, and are discussed in Nomenclature of Inorganic Chemistry, often referred to as the Red Book.
