Abstract
A series of Schiff-base complexes are prepared and characterized by elemental and thermal analyses, IR and electronic spectra, and magnetic measurements. SO2 interacted with solutions of the complexes forming complexes [M(SB)(SO2)2] where M = Mg(II), Cu(II), Mn(II), and [M(SB)(SO2)2]OH where M = Fe(III). These complexes are subjected to elemental and thermal analyses, conductance measurements and IR, electronic, and ESR spectra to indicate changes from interaction of SO2 with the Schiff-base complexes.
