New Schiff bases tetradentate ligands N2O2, were prepared from condensation chloroacetylaceton with diamine compounds (ethylenediamine, hydrazine carbothiohydrazide), then synthesis their transition metal complexes by reaction with Cu (II), and Co (II). All synthesized compounds were characterized by spectral techniques such as FTIR, 1HNMR and electronic spectra, and Mass spectra. The thermal stability and decomposition of complexes were studied. The antibacterial activity against gram-positive and gram-negative bacteria and calculate the diameter of inhibition zone (mm).
