Abstract
ABSTRACT. Fe(III) complex derived from sodium dodecyl benzene sulfonate (SDBS) has been synthesized and characterized using FT-IR, TGA, UV-Vis and VSM analysis. The complex structure was determined and illustrated. The study of thermogravimetric, optic and magnetic properties are reported and discussed. The bands in electronic spectrum involved a fully allowed transitions characteristic of Charge Transfer absorption from ligand to metal. The structural study revealed an octahedral geometry around the iron(III) ion. The complex obtained has the following formula [Fe(SDB)3]11H2O , where Fe(III) is linked to three bidentate ligands. This complexation is confirmed by layering FT-IR Ligand/Complex spectra. Moreover, the VSM analysis collected at room temperature exhibits antiferromagnetic behaviour referred to the anti-alignment of the magnetic moment of Fe3+.
