dc.description.abstractDiazo compounds were prepared by coupling of benzenediazonium chloride ions with 4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid mono sodium salt under alkaline conditions, and new Schiff bases H2L and H2L 1 were then obtained by the condensation of 4-amino-5-hydroxy-6-(2,5- dicholorophenylazo)-2,7-naphthalene disulfonic acid disodium salt and 4-amino-5-hydroxy-6-(2-nitrophenylazo)-2,7-naphthalenedisulfonic acid disodium salt with o-vanillin. New Cu(II), Ni(II) and Co(II) complexes of the Schiff base ligands were also prepared and characterized by IR, UV-Vis, 1H and 13C NMR (APT and DEPT) and atomic absorption spectroscopy, elemental analyses, thermogravimetric analysis, conductivity and magnetic measurements. In DMSO-d6 solutions, it was found that the azo-linked Schiff base ligands are in equilibrium with their corresponding and strongly prevailing hydrazone tautomers. The results suggested that the condensation of the azo-derivative compounds and o-vanillin in 1:1 molar ratio produces mononuclear Schiff base ligands with an ONO donor set.
