NOMENCLATURE FOR INORGANIC IONS AND LIGANDS Willem H. Koppenol The entries below were selected from Table IX of Connelly, N. G., Damhus, T., Hartshorn, R. M. and Hutton, A. T., Eds., Nomenclature of Inorganic Chemistry. IUPAC Recommendations 2005 , The Royal Society of Chemistry, 2005. Two changes were made: in the case of the hypohalides, the oxidohalogenate names are listed, not the new halooxygenate names. Thus, for BrO the still acceptable name “oxidobromate(1 )” is listed, not the more correct, but less palat- able, “bromooxygenate(1 )”. Similarly, and for reasons of consis- tency, ClO is not named oxygen (mono)chloride, but chlorine mono(o)oxide. The symbol ' ’ is used for dividing names when this is made necessary by a line break. When the name is reconstructed from the name given in the table, this symbol should be omitted. Thus, all hyphens in the table are true parts of the names. The sym- bols ‘>’ and ‘<’ placed next to an element symbol both denote two single bonds connecting the atom in question to two other atoms. For a given compound, the various systematic names, if applicable, are given in the order: stoichiometric names, substitutive names, ad - ditive names and hydrogen names. Acceptable names which are not entirely systematic (or not formed according to any of the systems mentioned above) are given at the end after a semicolon. No order of preference is implied by the order in which formulae and names are listed. Reprinted by permission of IUPAC.
