Synthesis and characterization of Schiff base complexes derived from 5-azophenysalicylaldehyde with Co(II) ion

In the present research 1,2-di[N-2-phenylthio-5-azophenylsalicylidene]ethane,(H2L1),1,3-di[N-2-phenylthio-5-azophenylsalicylidene]propane,(H2L2),1,4-di[N-2-phenylthio-5-azophenyl salicylidene]butane,(H2L3), were prepared. Reaction of H2L1, H2L2 and H2L3 with cobalt(II) acetate salt give CoL1, CoL2 and CoL3 complexes. The synthesized ligands and their complexes have been characterized by FT-IR,1HNMR ,elemental analysis, conductometry,UV-Vis. The coordination of imine nitrogens and phenolic oxygens to metal have been confirmed by FT-IR spectra and conductometry data.
