  • Coordination complex

    In chemistry, a coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal containing compounds, especially those of transition metals, are coordination complexes.
