ABSTRACT

The new series of two new hydrazone derivatives and their vanadium complexes have been synthesized bearing the formula V[DPTDH](BF4)2 and V[DCTDH](BF4)2,where M=V, DPTDH =2,6-diacetyl pyridine-N-N’-dithiodiacetoyl dihydrazone and DCTDH= 2,6-pyridine diacarbonyl dichloride-N-N’-dithiodiacetoyl dihydrazone and (BF4)=Tetrafluoroborate. The complexes were characterized on the basis of various spectroscopic techniques like FT-IR, UV & elemental analysis, and conductivity measurements. The octahedral geometry of synthesized complexes confirms by electronic data and IR spectra. The compounds were subjected to antimicrobial screening of ligand and hydrazone derivatives and their vanadium complexes against bacteria and fungi shows the complexes have been found to be manifold active biologically than the ligand.

Keywords: Hydrazone derivatives, Ligand, vanadium complexes, FT-IR, spectral and biological studies.
