What is a transition metal complex?

A transition metal complex is a central metal ion (for example platinum) surrounded by ligands.  Ligands are ions or small molecules that donate a pair of electrons to the central metal ion and surround it in a particular molecular geometry. Ligands can stand alone on their own in solution or in solid form or alternatively they can form a dative covalent bond with the metal.
