Which of the following complexes are heteroleptic?
(i) \[\ce{[Cr(NH3)6]^{3+}}\]
(ii) \[\ce{[Fe(NH3)4]Cl2]^+}\]
(iii) \[\ce{[Mn(CN)6]^{4-}}\]

उत्तर
(ii) \[\ce{[Fe(NH3)4]Cl2]^+}\]
(iv) \[\ce{[Co(NH3)4]Cl2]}\]
Explanation:
Complexes in which a metal is bound to more than one kind of donor groups are known as heteroleptic. This condition is satisfied by complexes mentioned at \[\ce{[Cr(NH3)6]^{3+}}\] and \[\ce{[Co(NH3)4]Cl2]}\] where the donor groups are \[\ce{NH3}\] and \[\ce{Cl2}\].
