new potentially ethylene glycol bridged metal complexes of schiff base: synthesis, spectral characterization, and biological activity

The synthesis of 2, 2’-[ethane-1,2dylbis (oxy)] dibenzaldehyde (n), thiocarbondisulfate ligands (w) and its metal complexes was studied in the work. synthetic reaction was accomplished in two stages by reacting salicylaldehyde and sodium carbonate in dmf media, and then 1,2-dibromoethane equivalent was added. by mixing hydrazine and cs2, w was synthesized. ligand (w) was produced by adding an ethanol metal chloride solution to a collection of metal ions. after that, the ligand n was introduced and dissolved. in dmf at a (0.5 m n: w) molar ratio to create five novel compounds. using physicochemical techniques (ft-ir, electron spectral analysis, mass, ¹h-nmr, and 13c nmr spectra, analysis of elements, magnetic susceptibility, and molar concentration), the isolated composition entity of the synthesized compounds was verified (conductivity). based on characterization data, octahedral compounds with the chemical formula [mlcl2] were formed. the antibacterial effect of the title components (ligands and complexes) was evaluated as an antioxidant when m= co (ll), ni (ll), cu (ll), zn (ll), and cd (ll). the results showed that the mineral compounds lost their activity relative to l.
