Naming Coordination Compounds

Postby mitalisharma2B » Mon Nov 27, 2017 11:29 pm

Within coordination compounds, when is "-ate" added to the central ion? When is the central ion just named as its elemental name?

Ex: cobalt vs. cobaltate
or platinum vs. platinate

If the overall compound is an anion, then you add the -ate, but if it's a cation then you don't add the -ate.

If the overall compound is neutral, is it still just the elemental name?

Another thing to remember is that if the symbol of the metal originates from a Latin name (as listed in appendix 2D), it will have a unique name. For example, an anionic compound with "Fe" would have the name "------ferrate" NOT "------ironate". This is stated in toolbox 17.1 on page 741 along with the other rules for naming coordination compounds.

The suffix "-ate" is added to the end of the ion when the ion has a negative charge, and it is not added when the ion has a positive charge.

The "ate" ending is added if the overall compound is an anion(a negatively charged ion)

If your transition metal (or central atom) is contained in the anion part of the compound, -ate will be added

Does anyone know the difference between writing CN as cyanido or cyano? The solution manual uses cyano to denote CN, but in table 17.4 it is listed as cyanido, does it matter which name is used?
