Summary of Changes in the IUPAC Recommendations on Naming Anionic Ligands

According to a recent recommendation [N. G. Connelly, T. Damhus, R. M. Hartshorn, A. T. Hutton (Eds.), Nomenclature of Inorganic Chemistry IUPAC Recommendations 2005, RSC Publishing, Cambridge, UK, 2005]:

"Names of anionic ligands, whether inorganic or organic, are modified to end in 'o'. In general, if the anion name ends in 'ide', 'ite' or 'ate', the final 'e' is replaced by 'o', giving 'ido', 'ito' and 'ato', respectively. It follows that halide ligands are named 'fluorido', 'chlorido', 'bromido' and 'iodido', and coordinated cyanide is named 'cyanido’. In its complexes, except for those of molecular hydrogen, hydrogen is always treated as anionic, and therefore 'hydrido' is used for hydrogen coordinating to all elements including boron."

"In the formulae for coordination entities, ligands are now ordered alphabetically according to first symbol of the abbreviation or formula used for the ligand, as written, irrespective of the charge."

For further details and examples, please see the "Frequently Asked Questions" section on the journal homepage and IUPAC publications and websites.
