Model Science College, Gwalior, MP., INDIA ABSTRACT The new series of two new hydrazone derivatives and their vanadium complexes have been synthesized bearing the formula M[DPDH](BF4)2 and M[DCDH](BF4)2, where M=V, DPDTPH= (2,6-diacetylpyridine-N,N’-Pyridine-2,6-dicarboxylic acid dihydrazone) and DCDTPH = (2,6- pyridine diacarbonyl di chloride- N-N’-Pyridine-2,6-dicarboxylic acid dihydrazone) and (BF4)=Tetrafluoroborate. The ligand and complexes have been analyzed for elemental analysis, spectral studies, and conductivity measurements. Different techniques like FT-IR, electronic data were used to investigate the structural features of the synthesized compounds. Electronic absorption and IR spectra indicate octahedral geometry. The antimicrobial activity 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. Key Words: Hydrazone derivatives, FT-IR, Spectral and antimicrobial Studies. INTRODUCTION
