Abstract: A novel Schiff base ligand derived from 2,2-bis(p -methoxyphenylamine) and
salicylicaldehyde and its transition metal complexes with Cu ( Ⅱ), Co ( Ⅱ) and Mn ( Ⅱ)
have been synthesized. Their spectral properties and electrochemical behavior were
investigated.
Keywords: Schiff base; transition metal complexes; synthesis; properties.
Introduction
During the past two decades, considerable attention has been paid to the chemistry of the metal
complexes of Schiff bases containing nitrogen and other donors [1-4]. This may be attributed to their
stability, biological activity [5] and potential applications in many fields such as oxidation catalysis [6],
electrochemistry [7], etc. Herein we report the synthesis of a novel Schiff base ligand (H2L) and its Cu
(II), Co (II) and Mn (II) complexes. Their spectral properties and electrochemical behavior were
investigated.
