SYNTHESIS AND STRUCTURAL STUDIES OF SOME COPPER (II) COMPLEXES OF SUBSTITUTED SALICYLALDEHYDE BENZOYL HYDRAZINE

Abstract

Spectrum investigations were used to synthesize and analyse a copper complex of type [Cu(II).nH2O(XSBH)]. In a variety of cultured human and animal cells, salicylaldehyde benzoyl hydrazine (SBH) is a potent inhibitor of DNA synthesis. When given to animals receiving transplanted fibrosarcoma, its Cu(II) complexes dramatically reduce tumor growth. We synthesized Cu(II) complexes of substituted salicylaldehyde benzoyl hydrazines (XSBH, X = 5-Cl, 3-NO2, 5-Br, 5-CH3) in order to produce more effective anticancer medicines. The chemical route method was employed in the creation of these complexes. The generated metal complexes were characterized using UV-visible spectroscopy to ascertain their chemical composition. The salicylaldehyde benzoyl hydrazine was revealed to participate in the coordination of Cu(II) in solutions by UV-vis spectra. The crucial information for a nanomaterial's employment in optoelectronic devices is its optical characteristics. The band gap energy is one of the parameters that affect a material's optical characteristics. Three steps can be taken to determine the band gap energy value from experimental UV-Vis absorbance spectrum data: smoothing the curve, determining the value of the baseline arrangement data, and calculating the band gap energy using the Tauc plot method built into the Origin software. We used the experimental UV-Vis absorbance spectra of the materials as input data. Our method yielded estimated band energy of 1.60 eV.
