Study Notes
Coordination Complexes
- In a coordination complex, the central atom or ion is the atom or ion bonded to several donor atoms, typically a metal ion.
Ligands
- A polydentate ligand is a molecule or ion that bonds to the central atom through several of its atoms, forming multiple bonds with the central atom.
- A polydentate ligand can form multiple bonds, typically more than one, with the central atom.
Central Atom and Ligand
- The atom within a ligand that is bonded to the central metal atom or ion is called the donor atom.
Types of Compounds
- Coordination complexes are a type of inorganic compound, especially those that include transition metals.
