Question

Write the IUPAC names of the following coordination compounds:
K₃[Al(C₂O₄)₃]

Answer 1

The IUPAC name of the coordination compound K₃[Al(C₂O₄)₃] is tripotassium tri(aluminium oxalate).

Step-by-step explanation:

The IUPAC name of the coordination compound K₃[Al(C₂O₄)₃] is tripotassium tri(aluminium oxalate).

To write the IUPAC name of a coordination compound, we follow certain rules:

1. Identify the central metal atom or ion, which in this case is aluminum (Al).
2. Name the ligands, which are the surrounding molecules or ions. In this compound, the ligand is oxalate (C₂O₄).
3. Write the metal atom/ion first, followed by the ligands in alphabetical order.
4. Use prefixes to indicate the number of each ligand.
5. Use parentheses to enclose the ligand name if it is a complex.

Using these rules, the IUPAC name for K₃[Al(C₂O₄)₃] is tripotassium tri(aluminium oxalate). In this compound, there are three oxalate ligands coordinated to one aluminum ion.
