The Schiff's base Metal Complexes of Co(II), Ni(II) and Cu(II) are synthesized in series. Schiff's Bases play a vital role in so many biological activities such as tuberculostatic, fungicidal and bacteriostatic and can act as potential chelating reagents. On the basis of elemental analysis, Infrared spectra, Electronic spectra, Magnetic moment data and Conductivity measurement data the ligand DOSC and DOTSC acts as bidentate manner and Co-ordination takes place through azomethine N and O/S donar atoms of either semicarbazone/thiosemicarbazone moiety. The remaining Co-ordination site are occupied by Cl-, Br-, I-, No3- and Clo4- and the geometry of the complexes are proposed to be Octahedral in nature. The major applications in the field of biological and pharmacological area such as analgesic, antipyretic, anti-inflammatory, anti-cancerous has made the study of Schiff base as visible source of significance for the betterment of human life.
