Species symbols should be entered in full, i.e. without truncation. Ambiguities will cause the search to fail.

Species symbols are a sequence of characters that uniquely represent the species concerned. For example (without the quotes), 'Gly-1' represents 'glycinate', 'NH3' represents 'ammonia', 'EDTA-4' represents 'ethylenediaminetetraacetate' and 'CO3-2' represents 'carbonate'.

The above examples all refer to 'primitive species symbols'. In the case of this search, they can also be combined together, using underscore characters '_', to form 'composite species symbols', as in the example above for sodium chloride solid.

You can establish the symbol of any ligand that you require through the 'Find Species Symbol' search on the previous page.
