The complexes are of the formula [M(L)X2]. Where (M = Co (II), Ni (II), Cu (II), Zn (II), Hg (II) and Cd (II) and X = Cl, Br, NO3). Tetrahedral geometry has been proposed to these metal complexes with the help of magnetic measurements, elemental analysis, chemical stoichiometry and spectroscopic data. Antibacterial activity of the ligand and its metal complexes were screened against Eschereschi coli, Klebsiella pneumonia, Proteus mirabilis, Proteus vulhari, Streptococcus pneumonia, Salmonella typhi, Bacillus anthrax, Streptococcus fecalis and Staphylococcus aureus. Metal complexes were found to be active against Eschereschi coli, Klebsiella pneumonia, Proteus mirabilis and Proteus vulharis.
