New neutral Schiff base complexes of Cu(II), Co(II), Ni(II) and Zn(II) derived from 4-aminoantipyrine and N-(1-morpholinobenzyl)acetamide (Mannich base) have been synthesized. The structural features of the complexes have been confirmed by microanalytical data, IR, UV-Vis., NMR, EPR, and CV techniques. Electronic absorption spectra of the complexes indicate an octahedral geometry around the metal ion. Their magnetic susceptibility measurements and low conductance data provide evidence for the monomeric and neutral natures of the complexes respectively. The electrochemical behaviour, the anodic and cathodic potential and the number of electrons transferred were calculated using cyclic voltammogram. The X-band EPR spectrum of copper complex in DMSO at 300 K and 77 K was recorded and its salient features are reported. The antimicrobial activity of the ligand and its complexes has been extensively studied on microorganisms such as Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa and the fungi Aspergillus niger and Rhizoctonia bataicola by well-diffusion technique using DMF as solvent. It has been found that all the complexes have higher activity than the free ligand and the standard.
