Write the IUPAC name of the following coordination compound `[NiCl_(4)]^(2-).`

Explanation

To determine the IUPAC name of the coordination compound \([NiCl_4]^{2-}\), we will follow these steps:

### Step 1: Determine the oxidation state of Nickel (Ni)
Let the oxidation state of Nickel be \(X\). The oxidation state of Chlorine (Cl) is \(-1\). Since there are 4 Chlorine atoms, their total contribution to the charge is \(4 \times (-1) = -4\).

The overall charge of the complex ion is \(-2\). Therefore, we can set up the equation:

\[ X + (-4) = -2 \]
