Define homoleptic and heteroleptic complexes. Give example for each.
Complexes containing only one type of ligands are known as homoleptic complexes
Eg: [Co(NH3)6]Cl3 , K2[Ni(CN)4]
Complexes containing more than one kind of ligands are known as heteroleptic complexes
Eg: [Co(NH3)3Cl3] , [Fe(H2O)4Cl2] Cl
