Tetradentate bidentate Schiff base (L1) from 4-amino-1.5-dimethyl-2-phenyl-1.2-dihydropyrazol-3-one and 2-(1H-indol-3-yl)-ethylamine and benzene-1.4-dicarbaldehyde was
synthesized and characterized as novel antioxidants. The Schiff base and its metal complexes
Mn(II), Co(II),Cu(II), Zn(II), Cd(II) and Re(V) have been characterized by elemental
microanalysis, metal content, chloride-containing, molar conductance, FT-IR, 1H-NMR, UVVis spectroscopy, magnetic susceptibility, mass spectra (MS), and thermal analysis (TGA).
The structures of the prepared compounds were observed by antioxidant activities of the
Schiff bases derivatives were investigated due to the imine group (-C=N-) and promising
results were obtained. The results confirmed that c
