Synthesis and Characterization of Schiff Base Derived From Chitosan and Its Complexes With (Co+2, Ni+2 and Cu+2)

Abstract

In this research, new Schiff base is derived from chitosan O-nitrobenzyldehyde and itscomplexes were synthesized. All compounds were characterized by FT-IR, UV-Visible, TGA,DTA, TG and molar conductivity with melting point.The results showed that Schiff base was coordinated via nitrogen atom azomethine with thecenter metal ions Co+2,Ni+2 and Cu+2 behaving monodentate ligand and forming complexeswith molecular formula [M(L)Cl2H2O] The tetrahedral geometrical was suggested for allprepared complexes based on the characterization data for all techniques.M = Co+2, Ni+2,Cu+2
