Write the coordination isomer of `[Cu(NH_3)_4][PtCl_4]`.

Explanation

To find the coordination isomer of the complex \([Cu(NH_3)_4][PtCl_4]\), we need to understand what coordination isomers are. Coordination isomers occur when the ligands are exchanged between the cation and anion of a coordination compound, while maintaining the same overall molecular formula.

### Step-by-Step Solution:

1. **Identify the Components of the Complex**:
- The given complex is \([Cu(NH_3)_4][PtCl_4]\).
- Here, \([Cu(NH_3)_4]^{2+}\) is the cation and \([PtCl_4]^{2-}\) is the anion.
