Abstract
New-type Schiff bases were prepared: [2-(benzoxazol-2-yl)-hydrazinyl diene][-2,1-diphenyl-N-(6-methoxybenzothiazol-2-yl)-2,1-diphenylethane]. -1-amine (L) of the mixture. 2-mercaptobenzoxazole was dissolved with hydrazine in absolute ethanol as a first stage to form compound A. while the ligand was obtained in its final from the reaction of compound A with both benzal and 2-amino-6-methoxybenzothiazole. The complex of Ni(II) and Pd(II) was prepared by reacting palladium chloride and nickel chloride with ligand L. The structure of the prepared ligand and its complexes was diagnosed using several spectroscopic techniques, such as FT-IR, UV-Visible, and 1H-NMR , in addition to FE-SEM, atomic absorption, molar conductivity, and elements. Microanalysis and measurements of magnetic susceptibility and melting points Molar conductivity measurements of palladium (II) and nickel (II) complexes showed that they have an ionic property of (1:2). It was found that the azomethine in the benzoxazole and benzothiazole rings, as well as the nitrogen atoms in the two azomethine groups in the Schiff base, coordinate with the metal ion in the FT-IR spectra of the compound. Based on measurements of sensitivity to ultraviolet, visible, and magnetic radiation, the complexes were shown to have geometries such as palladium (II) being square and planar and nickel (II) being octahedral. It can be used to study its antibacterial effect, and it showed good results.
