Coordination number

उत्तर
It is the number of ligand donor atoms to which the metal is directly bonded. For example:
- [Cu(NH3)4]2+: In this complex, the coordination number of copper (Cu2+) is 4 because there are four ammonia (NH3) molecules bonded to the metal ion.
- [Fe(CN)6]4−: Here, the coordination number of iron (Fe2+) is 6, as six cyanide (CN−) ions are coordinated to the iron ion.
