Five Cu(II) complexes are tridentate Schiff bases amino acids ligands derived from condensation 3–methoxysalicylaldehyde (MS) or 4-diethylaminosalicylaldehyde (DS) with α-amino acids (L-phenylalanine(P), L-histidine (H), DL-tryptophane (T)). All ligands are analyzed by 1HNMR and 13CNMR. The investigated complexes have been prepared and characterized by elemental analysis, infrared spectra, ultraviolet-visible and thermal analysis in dynamic air atmosphere (40ml / min) at a ...
