A new series of vanadyl(IV), manganese(II), iron(II), nickel(II) and copper(II) complexes of N-[phenyl(pyrrolidin-1-yl)methyl]benzamide(PBB) have been synthesized and characterized by elemental analysis, molar conductance, IR, electronic, EPR spectra and magnetic measurements. Conductance measurements indicate that the above complexes are non-electrolytes. The spectral data show that, the ligand behaves as a neutral bidentate, bonded to metal ions via the carbonyl oxygen of acetamide group and azomethine nitrogen of morpholine moiety. Magnetic susceptibility measurements indicate tetrahedral geometry for NiII chloro, sulphato and CuII nitrato complexes and octahedral geometry for the rest. EPR spectral data suggest ionic link between metal center and the Mannich base ligand. IR studies indicate the presence of water molecules in some of the complexes. The antimicrobial studies show that the CuII complex is more active than others.
