Which of the following complexes are heteroleptic ?A. `[Cr(NH_(3))_(6)]^(3+)`B. `[Fe(NH_(3))_(4) Cl_(2)]^(+)`C. `[Mn(CN)_(6)]^(4-)`D. `[Co(NH_(3))_(4)Cl_(2)]`

Which of the following complexes are heteroleptic ?A. `[Cr(NH_(3))_(6)

1.	Which of the following complexes are heteroleptic ?A. `[Cr(NH_(3))_(6)]^(3+)`B. `[Fe(NH_(3))_(4) Cl_(2)]^(+)`C. `[Mn(CN)_(6)]^(4-)`D. `[Co(NH_(3))_(4)Cl_(2)]`
Answer» Correct Answer - B::D Heteropleptic complexes Coordination complexes which contain more than one type of ligands are known as heteropletic complexes. e.g., `[Fe(NH_(3))_(4)Cl_(2)]^(+)` contain `NH_(3)` and `Cl` as a ligand is as heteroleptic complex. Similarly `[Co(NH_(3))_(4)Cl_(2)]` contain `NH_(3)` and `Cl` as ligand is also a heteroleptic complex. Hence, options (b) and (d) are correct choices.
