- A complex ion has
- A central metal cation
- Surrounded by a group of anions or molecules
- These are known as ligands
- Compounds that contain complex ions are called coordination compounds
Ligands:
- Examples include
- Anions (E.g Cl– or CN–)
- Polar molecules (E.g H2O or NH3)
- Co-ordinate covalent bonds form between the ligands and the transition metal ion
- Uses the lone pair electrons of the ligand
