The Schiff base 2,5-dihydroxyacetophenone isonicotinoyl hydrazone (H2L) has been synthesized by condensation of 2,5-dihydroxyacetophenone with isonicotinoyl hydrazide in ethanol. Metal complexes of the Schiff base were prepared from salts of Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO2(VI). Characterization of the ligand and its metal complexes were carried out by elemental analysis, molar conductivity, magnetic susceptibility measurements, IR, 1H NMR, electronic and thermogravimetric analysis in air. The Schiff base behaves as flexidentate ligand and commonly coordinates through the oxygen atom of the deprotonated phenolic group and the nitrogen atom of azomethine group. The thermal data have been analyzed for the kinetic parameters by Broido and Horowitz-Metzger methods. All the compounds were also screened for their antimicrobial activity by agar cup-plate method against various organisms and the results have been compared.
