Verified Solution

Answer & Solution

Correct Answer

(B) \(\left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_5(\mathrm{NSC})\right]^{2+}\)

Step-by-step Solution

Detailed explanation

In \(\left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_5(\mathrm{NSC})\right]^{2+}\), two different ligands are attached to the central metal ion. Therefore, it is a heteroleptic complex.
