Which of the following complex is homoleptic?
- \([ \text{Ni(CN)}_4 ]^{2-}\)
- \([ \text{Ni(NH}_3)_2\text{Cl}_2 ]\)
- \([ \text{Fe(NH}_3)_4\text{Cl}_2 ]^{+}\)
- \([ \text{Co(NH}_3)_4\text{Cl}_2 ]^{+}\)
The Correct Option is A
Solution and Explanation
A homoleptic complex has all ligands identical. In [Ni(CN)4]2−, all ligands are cyanide ions, making it homoleptic.
