i PREFACE The ability of Schiff bases to form complexes with metal
... The ability of Schiff bases to form complexes with metal ions has been well established. This is due to the presence of lone pair of electrons on the nitrogen atom and of the general electron donating character of the double bond. They also form five or, six membered stable chelates with metals, if ...

Coordination complex
In chemistry, a coordination complex or metal 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.
