INVESTIGATE THE INHIBITION AGAINST BACTERIA BY USING SCHIFF BACE COMPLEXES

Abstract

FT-IR, UV-vis, 1H-NMR, 13C, and mass spectrometry were used to characterize the ligand, and complexes it was discovered that the synthesized ligand was donation as (NO)1 . The produced ligand reacted with a few transition elements, such as Cu2+, Co2+, and Ni2+, to form complexes, which were then characterized by conductivity, FT-IR, UV-vis, and spectroscopy. Low values for (IR), mass spectrum, and molar conductivity suggest that the complexes lack negative radicals outside of the coordination sphere. The complexes were also evaluated for their magnetic properties using thermogravimetric analysis (TGA), which revealed that the cobalt (II), copper (II), and nickel (II) complexes have paramagnetic properties and adopt an octahedral geometry. TGA was also used to determine whether the complexes contain water molecules coordinated to the central atom. The complexes' structural formulae were suggested using the various characterization techniques. The compounds under investigation proved efficient against both positive and negative bacteria, allowing us to move forward with theoretical and biological research to determine the precise location where bacteria's protein’s function.
