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. Molecules 2003, 8
