Ligand names and formulae

Many familiar small molecules and anions act as ligands in the formation of metal complex ions. In getting to grips with the slightly complex but highly systematic nomenclature of these complex ions it is essential to be familiar with ligand names, which may differ substantially from their usual names. After studying the table you can try this ligand naming exercise.
