Abstract
A series of some mononuclear oxovanadium(IV) complexes have been synthesized by the reactions of oxovanadium(IV) sulfate with Schiff base ligands derived from 3-(phenyl / substituted phenyl)-4-amino-5-mercapto-1, 2, 4-triazoles of aromatic carboxylic acids and benzyl. The complexes were analyzed by different spectroscopic methods (FTIR, UV-Vis., EPR), X-ray diffraction (XRD) analysis, elemental analysis, conductivity measurement, and cyclic voltammetry (CV) analysis. The non-electrolytic nature of the complexes was determined on the basis of the molar conductance values. The powder X-ray diffraction pattern has also been used to determine crystal size and type. On the basis of the physicochemical data, the tentative square- pyramidal geometry of the complexes has been proposed. In vitro antibacterial andantidiabeticproperties by alpha amylase inhibition activities of the selected complexes have also been determined.
