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 ...
