उत्तर
Heteroleptic refers to a coordination complex where the central metal ion is coordinated with more than one type of ligand. For example:
- [CuCl4(NH3)2]2+: In this complex, copper (Cu2+) is coordinated with both chloride (Cl−) and ammonia (NH3) ligands, making it a heteroleptic complex.
- [Cr(H2O)6Cl2]2+: In this complex, chromium (Cr3+) is coordinated with six water (H2O) molecules and two chloride (Cl−) ions, which also makes it heteroleptic.
