Write the IUPAC names of the following complexes :
`K_(3)[Al(C_(2)O_(4))_(3)]`

Explanation

To write the IUPAC name of the complex \( K_3[Al(C_2O_4)_3] \), we will follow these steps:

### Step 1: Identify the components of the complex
The complex consists of a potassium ion (K) outside the coordination sphere and an aluminum ion (Al) coordinated with three oxalate ligands (\(C_2O_4^{2-}\)).

### Step 2: Name the ligands
The oxalate ion is a bidentate ligand, which means it can bind to the metal at two sites. The name of the oxalate ligand is "oxalato". Since there are three oxalate ligands, we will use the prefix "tri-" to indicate this.
