Abstract: The present study deals with the synthesis of an N-phenylbenzal-diphenylamine Schiff base derived from Benzaldehyde and Diphenylamine. This Schiff base is formed by the condensation of Benzaldehyde and diphenylamine. Schiff bases are known for their diverse biological and coordination properties due to the presence of an azomethine group. The Ni (II) complex of this SB was obtained through refluxing the SB with the metal salt in ethanol. Both the SB and complexes were confirmed via spectroscopic and physicochemical analyses. The UV-Vis spectra of Ni-bis-N-phenylbenzal-diphenylamine chloride complexes consistently showed absorption bands around 291.4 nm. These complexes exhibited strong antibacterial activity against Escherichia coli in disc diffusion tests. UV-Vis spectroscopy aided their synthesis and characterization. These results highlight the significant antimicrobial potential of Schiff base metal complexes.
