Transition metal complexes of Schiff bases (L1) derived from the condensation of 4-aminoantipyrine, 4-nitrobenzaldehyde and acetylacetone has been synthesized by non-template method and characterized by elemental analysis, IR, 1H NMR, EPR spectroscopy, conductometry, thermal analysis, magnetic measurements and a microbial study. The magnetic measurements and EPR spectral data of the complexes suggest a square-planar geometry around the central metal ion. The molar conductance data revealed that all the complexes were electrolytes in the ratio 1;2 (metal:ligand). The thermal stability of the complexes was studied by thermogravimetry and the decomposing schemes of the complexes are given. The ligands and their metal complexes were screened for antimicrobial activity against S. typhi, S. aureus, E. coli and B. subtilis.
