Give an example of ionization isomerism.

Explanation

### Step-by-Step Solution:

**Step 1: Understand Ionization Isomerism**
- Ionization isomerism occurs when two or more compounds have the same molecular formula but produce different ions in solution. This is due to the different arrangements of ligands around the central metal ion.

**Step 2: Identify an Example**
- A classic example of ionization isomerism involves coordination compounds.
