Explain with two examples the following
homoleptic and heteroleptic complexes.

Explanation

Homoleptic complexes : Complexes in which a metal is bound to only one kind of donor groups, e-g-, `[Co(NH_3)_6]^(3+)`, are known as homoleptic complexes.
Heteropletic complexes : Complexes in which a metal is bound to more than one kind of donor groups, e.g., `[Co(NH_3)_4Cl_2]^(+)` are known as heteroleptic complexes
