Abstract
Metal complexes ofTi(III), VO(IV), Cr(III), Mn(III), Fe(III) and Zr(IV) with Schiffbase derived from 2-hydroxy-5-methylacetophenone and benzoyl hydrazide have been synthesized and characterized on the basis of elemental analysis, infrared spectra, magnetic moment, electronic spectra and thermogravimetric studies. Various kinetic parameters evaluated from thermal decomposition data and thermal stabilities of the complexes are also reported. The antibacterial and antifungal activities of 2-hydroxy-5-methylacetophenone benzoylhydrazone (HMABH) and its complexes have been investigated against various bacterial strains using the disc diffusion technique. All complexes exhibit good biological activity as compared to free ligand. Solid-state electrical conductivity of ligand and its complexes have also been studied over a wide range of temperature and it was found that compounds exhibit semiconducting behavior in the studied range.
