New transition metal complexes [Ni(L)2], [Zn(L)Cl], [Zn(L)2] and [Cd(L)2] were synthesized from 3-bromo-benzoic acid (phenyl-pyridin-2-yl-methylene)-hydrazide (3Bbpph) and 4-bromo-benzoic acid (phenyl-pyridin-2-yl-methylene)-hydrazide (4Bbpph) ligands and were characterized by different physicochemical and spectral studies - IR, elemental, UV Visible, 1H NMR spectra and mass analysis. The data revealed the presence of tetra-coordinate [Zn (L)Cl], whereas [Ni(L)2], [Zn(L)2], and [Cd(L)2] complexes consist of metal ion coordinated with two molecules of ligand to form octahedral geometry. The ligands act as monobasic, tridentate, and coordinated through enolate-O, azomethine-N, and pyridyl-N atoms. The antimicrobial activity of the ligands and metal complexes was investigated against Staphylococcus Aureus, Streptococcus Pyogenes, Escherichia coli, Salmonella typhi, Candida Albicans and Trichophyton Rubrum which revealed that the metal complexes exhibit greater activity than the parent ligands.

Transition metal complexes of Cu(II), Co(II), Ni(II), Zn(II), Cd(II) and Mn(II) have been synthesized with the Schiff base ligand 5-Sub-N-(2-mercaptophenyl)salicylideneimine. Elemental analysis of these complexes suggest that these metal ions forms complexes of type ML(H2O)stoichiometry for Cu(II), Co(II), Ni(II), Zn(II), Cd(II) and Mn(II). The ligand behaves as tridentate and forms coordinate bonds through O, S and N atoms. Magnetic susceptibility, IR, UV – Visible, Mass and ESR spectral studies suggest that Cu(II), Ni(II) complexes posses square planar geometry, whereas Co(II), Zn(II), Cd(II) and Mn(II) complexes posses tetrahedral geometry. The complexes were tested for their antimicrobial activity against the bacterial strains Staphylococcus aureus and Bacillus subtilis.The Schiff base metal complexes evaluated for their antifungal activity against the fungi A. niger and C. oxysporum. The DNA cleavage studies of Schiff base complexes werestudied using Calf – Thymus DNA by agarose gel electrophoresis method.
