This paper presents the formation of Schiff base by the condensation of primary amine with carbonyl compound. Schiff base complexes play a major role in stereo chemical model and coordination chemistry to their preparation accessibility diversity and structural variability1. Co(II) complexes with chelating ligand containing N,O,S as a donor atoms have attracted special attention. The Schiff base ligand as well as cobalt2 complexes were synthesized carefully. The ligands were usually Nicotinamide Semicarbazone as well as Thiosemicarbazones3. The ligand their Co(II) Complexes were synthesized and characterized by elemental analysis, conductivity measurement, study of electronic, IR, NMR and eprSpectra. Conductivity data showed the non-electrolytic nature of ligand. Distorted Octahedral Geometry were proposed for Co(II) Complexes5. Their Complexes are used as model molecules for oxygen carrier crystal.
