SYNTHESIS AND CHARACTERIZATION OF SCHIFF BASE AND ITS TRANSITION METAL COMPLEXES DERIVED FROM 3-ETHOXYSALICYLALDEHYDE AND P-TOLUIDINE

By Micro elemental analysis, FTIR, Ultra Violet-Visible, Thermal analysis, 1 H & 13 C NMR, ESR and Antimicrobial studies a total of four new metal complex derivatives of 2-((p-tolyliminomethyl)-6-ethoxyphenol (EST-L) with the metal ions Mn(II), Co(II), Cu(II) and Zn(II) have been synthesized and characterized quantitatively and qualitatively.It is shown through the spectral study that the geometrical, structural and octahedral geometries for Mn(II), Co(II), Cu(II) complexes and square planar for Zn(II) complex respectively.The presence of unpaired electrons in dx 2 -y 2 orbital and distortion in octahedral geometry of Cu(II) complex is confirmed by the ESR spectra.Under the biological evaluation, all the synthesized compounds were closed.
