Formation, Characterization and Thermal Study of Novel Schiff Base Ligand from Sulfonic Acid and Its Complexes with Co(II), Ni(II), Cu(II), Zn(II) and Hg(II) Type NO

The new liganed Schiff base named [(E)-۳-hydroxy-۴-((۳,۴,۵-trimethoxybenzylidene)amino) naphthalene-۱- sulfonic acid] was synthesized from ۳,۴,۵-trimethoxybenzyldehyde and ۱-amino-۲-aphthol-۴-sulfonic acid in equal molar ratio. A series of new metal complexes' of the common molecular formulation [M(L)۲(H۲O)۲].H۲O are synthesized and characterized by IR, UV–Vis spectra,  mass spectra, atomic absorption, elemental analyses, chloride content, magnetic susceptibility and conductivity measurements as well as thermo gravimetric analysis (TGA, DSC). Consistent with results of the magnetic and spectral studies, the advised geometrical structures for all of the prepared complexes have been octahedral formula.
