Synthesis and characterization of Schiff base derived from chitosan and its complexes with (Co+2, Ni+2 and Cu+2)‎

الملخص EN

In this research, new Schiff base is derived from chitosan O-nitrobenzyldehyde and its complexes 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 the center metal ions Co+2,Ni+2 and Cu+2 behaving monodentate ligand and forming complexes with molecular formula [M(L)Cl2H2O] The tetrahedral geometrical was suggested for all prepared complexes based on the characterization data for all techniques.

M = Co+2, Ni+2,Cu+2
