Co (II), Ni (II), Cu (II) and Mn (II) complexes of Schiff bases have been prepared and characterized by their physical, spectral and analytical data. The newly synthesized metal complexes having a composition [M (L) 2X2], where M=Co (II), Ni (II), Cu (II) and Mn (II), Where, L=monodentate ligand (derived from p-chloro benzaldehyde, p-nitro benzaldehyde or p-methoxy benzaldehyde with vinyl aniline or allyl amine) X =Cl shows a square planar geometry. In order to evaluate the biological activity of Schiff bases and their metal complexes, the Schiff-bases and their new metal complexes have been screened for their antibacterial and antifungal activity against bacterial species like- Escherichia coli, Staphylococcus aureus, Klebsiella and Psuedomonas and as well as fungal species like- Candida albicans or Candida krusei.
