The Coordination Chemistry of Oxygen Transport

Chelation therapy works by the administration of a ligand, which binds to metal ions already in the bo. Many drugs, including cisplatin [ Chapter 3, Applying What You ve Learned], are themselves coordination compounds in which the central metal ion binds to electron-rich sites (such as oxygen or sulfur atoms) in biological molecules. 

Coordinatum cotiqwunds contain coordinate covalent bonds between a metal ion (often a transition metal ion) and two or more polar molecules or ions. 

The molecules or anions that surround a metal in a coordination complex are called Ugands. 

Many coordination compounds consist of a complex ion and a counter ion. 

Transition metals are those that have incompletely filled d subshells— or that give rise to ions with incompletely filled d subshells.
