A new Schiff base, salicyalidene – 3,4 – dimethyl aniline has been synthesized from salicyaldehyde and 3,4 – dimethyle aniline metal complexes of the Schiff base were prepared from metal salts of Co(II) and Cu(II) in an alcoholic medium. The complexes were non – electrolytes in DMSO. The chemical structures of the Schiff base ligand and its metal complexes were confirmed by various spectroscopic studies like IR, UV – VIS, HNMR, elemental analysis molar conductance and magnetic susceptibility measurements. On the basis of elemental and spectral studies square planar geometry was assigned to these complexes in the light of these results. It is suggested that this ligand acts as bidentate and coordinates to each metal ion by azomethine nitrogen and phenolic oxygen atom. The Schiff base and its complexes have been tested for their antimicrobial activity by using disc diffusion method.
