Study Notes
Coordination Complexes
- A coordination complex is a central metal atom or ion bonded to one or more ligands, which are molecules or ions that donate one or more pairs of electrons.
Ligands
- The atom within a ligand that is bonded to the central metal atom or ion is called the donor atom.
Polydentate Ligands
- A polydentate ligand is a ligand that has multiple donor atoms, allowing it to form multiple bonds with the central metal atom or ion.
Coordination Sphere
- The coordination sphere in a coordination complex refers to the central metal atom or ion and the surrounding ligands that are directly bonded to it.
Coordinate Covalent Bonds
- Coordinate covalent bonds in coordination complexes refer to the bonds formed between the central metal atom or ion and the ligands, where the ligands donate one or more pairs of electrons to form a covalent bond.
