Which of the following is an example of homoleptic complex?
- ${[Co(NH_3)_6]Cl_3}$
- ${[Pt(NH_3)_2Cl_2]}$
- ${[Co(NH_3)_4Cl_2]}$
- ${[Co(NH_3)_5Cl]Cl_2}$
The Correct Option is A
Solution and Explanation
Homoleptic complexes are coordination compounds in which only one type of ligand is coordinated to the central metal ion.
So, the correct option is (A): \({[Co(NH_3)_6]Cl_3}\)

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
