4DescriptionAbstract The vanadium(V) peroxo complexes containing aroylhydrazone ligands having composition Na[VO(O2)2L-L].2H2O (where L-L = BFMH, BTEH, BTMH, BPMH, BAMH and BCMH) are reported. The complexes were synthesized by stirring vanadium pentoxide with excess of 30% aqueous-H2O2 followed by treatment with methanolic solution of the ligand and finally maintained the pH of the reaction mixture by adding dilute solution of sodium hydroxide. The complexes have been characterized by various physicochemical techniques, viz. elemental analysis, molar conductivity, magnetic susceptibility measurements, infra red, electronic, mass, 1H NMR spectral and TGA/DTA studies. These studies revealed that the complexes are uni-univalent electrolytes and diamagnetic in nature. The ligands are bound to metal in a bidentate mode through carbonyl oxygen or thiocarbonyl sulphur and nitrogen of amine group. Thermal analysis results provide conclusive evidence for the presence of two molecules of lattice water in the complexes. Mass spectra confirm the molecular mass of the complexes. Antifungal activity of complexes revealed enhanced activity of complexes as compared to corresponding free ligands. Molecular modeling has been used to suggest the energy minimized structures for the complexes.
