Abstract:

Schiff base compounds are synthesized by the condensation of amines with carbonyl/aldehyde groups. These compounds and their metal complexes have been synthesized because those are able to stabilize metal ions in various oxidation states [1]. Schiff base complexes are often utilized as catalysts with high performance for producing organic compounds. A well known series of the complexes containing a tetradentate Schiff base moiety can be used as oxygen carriers which are useful models for biochemical processes [2].In this reseach project at the first step, a new tetradentate Schiff base ligand of N,N-bis-(2-acetylpyridine)-1,8-diamino naphthalene, (L) was synthesized. The ligand was confirmed by various analytical technics. At the second step, its Fe(II), Ni(II), Cu(II), and Zn(II) complexes were synthesized in a 1:1 molar ratio. The mentioned complexes investigated and characterized by using Gouy balance, elemental and thermal analysis, conductometry, and FT-IR, UV-Vis, spectroscopic techniques. FT-IR spectra of all the complexes exhibit the imine (C=N) bond which is shifted with respect to the imine peak of the Schiff base ligand. Besides, all the complexes, except for Zn(II), are paramagnetic with the appropriate unpaired electrons
