IUPAC Nomenclature of Coordination Compound
The IUPAC name of \( \text{K}_3[\text{Co}(\text{C}_2\text{O}_4)_3] \) is Potassium trioxalatocobaltate(III).
The oxalate anion ( \( \text{C}_2\text{O}_4^{2-} \) ) is a bidentate ligand, and the prefix "tri" indicates there are three oxalate ligands.
The complex anion is \( [\text{Co}(\text{C}_2\text{O}_4)_3]^{3-} \), and since the potassium ion has a +1 charge, there must be three potassium ions to balance the charge.
The oxidation state of cobalt is +3, indicated by the Roman numeral (III).

Concepts Used:
Nomenclature of Coordination Compounds
Nomenclature of Coordination Compounds is important in Coordination Chemistry because of the need to have an unambiguous method of describing formulas and writing systematic names, particularly when dealing with isomers.
We can apply the following formulas:
- On the very first the central atom is listed.
- Ligands are then listed in alphabetical order and their placement in the list does not depend on their charge.
- Polydentate ligands are also listed alphabetically. In such a case of an abbreviated ligand, the first letter of the abbreviation is used to determine the position of the ligand in alphabetical order.
- The formula for the entire coordination entity is enclosed in square brackets whether charged or not. The formulas are enclosed in parentheses when ligands are polyatomic. Ligand abbreviations are also enclosed in parentheses.
- Within a coordination sphere, there should be no space between the ligands and the metal.
- When the formula of a charged coordination entity is to be written without that of the counter-ions, the charge is indicated outside the square brackets as a right superscript with the number before the sign. For example, [Co(CN)6]3-, [Cr(H2O)6]3+, etc.
- The charge of the anion(s) balances the charge of the cation(s).
