Define the following terms: Homoleptic and heteroleptic complexes.

(N/A) Homoleptic and heteroleptic complexes:
$(a)$ Homoleptic Complexes: Complexes in which a metal is bound to only one kind of donor groups are known as homoleptic.
Example: $[Co(NH_{3})_{6}]^{3+}, [Ni(CO)_{4}]$.
$(b)$ Heteroleptic Complexes: Complexes in which a metal is bound to more than one kind of donor groups are known as heteroleptic.
Example: $[Co(NH_{3})_{4}Cl_{2}]^{+}, [Pt(NH_{3})_{2}Cl_{2}]$.
