Active carbonyl and imino groups (R-C=N-) are condensed to produce Schiff bases. Schiff bases are very proficient to stabilize several metals in different oxidation states. Since nitrogen contains lone pair electrons, the imines that are produced can combine with metal to create a complex. The Schiff bases ligand was produced and used in this work to construct the metal complexes of Cu (II) and Zn (II) ions. The Significance of metal (II) complexes has been thoroughly characterized using various physical, analytical and spectroscopic techniques and biological characteristics. The spectrum data obtained from the analytical characterization of FT-IR, UV-visible, ESR, and TGA procedures confirmed the postulated structure. The diamagnetic and paramagnetic properties of Cu(II) and Zn(II) complexes have been confirmed using ESR research. The chelation between ligands and the metal can be confirmed by analyzing FT-IR and UV-visible spectra. The coordination sphere of the complexes is devoid of ions, as indicated by the low conductance measurements. The TGA's thermal tests supported the complex's structural configuration, revealing its breakdown kinetics and the subsequent release of various ions at different temperatures. All of the spectrum evidence indicated the presence of complexes with a square pyramidal form. The bacteria, including Staphylococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa, and Escherichia coli, exhibited a moderate susceptibility to the complexes.
