Write the IUPAC names of the complex `[Pt(en)_(2)Cl_(2)]^(2+)` . What type of isomerism is shown by the complex ?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Determine the oxidation state of Platinum (Pt)
- The complex is given as \([Pt(en)_{2}Cl_{2}]^{2+}\).
- Let the oxidation state of Platinum be \(x\).
- Ethane-1,2-diamine (en) is a neutral ligand, so it contributes 0 to the charge.
- Each chloride ion (Cl) has a charge of -1, and there are 2 chloride ions, contributing a total of -2.
- The overall charge of the complex is +2.
