What to Focus On
- Coordination compounds are also called complex compounds or Werner complexes.
- Ligands are electron pair donors.
- Coordination compounds retain identity in water.
- Denticity means the number of donor atoms in a ligand.
- Ambident ligands have more than one possible donor atom.
- Chelates are more stable than ordinary monodentate complexes.
- Primary valency equals oxidation state.
- Secondary valency equals coordination number.
- Secondary valencies are directional.
Common Mistakes to Avoid
A coordination compound always breaks into its ions completely in water, just like a double salt.
The oxidation number of the central metal is always the same as the charge on the complex ion.
All ligands in a complex are named in the order of charge: negative first, then neutral, then positive.
