Microwave synthesis and physicochemical characterization of vo(iv) and co(ii)schiff base metal complexes

The Sustainable/Greener approach is prioritized over the conventional approach because of its environment-friendly, less time-consuming, less energy-consuming, less hazardous compounds synthesis, and low expenditure. New Schiff base and their VO(IV) and Co(II) complexes formed by the condensation of 4-dimethyl aminobenzaldehyde and 3-chloro-4-fluoroaniline have been synthesized by conventional as well as microwave methods. These compounds have been synthesized by conventional as well as microwave methods. These compounds have been characterized by elemental analysis, FT-IR, FAB-mass, molar conductance, electronic spectra, magnetic susceptibility, thermal and XRD analysis. The complexes are coloured and stable in air. Analytical data revealed that all the complexes exhibited 1:2 (metal:ligand) ratio with the coordination 4. FAB-mass and thermal data show degradation pattern of the complexes. XRD patterns indicate crystalline nature for the complexes.
