Synthesis, characterization and structural study of Fe(III) complex derived from sodium dodecyl benzene sulfonate

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+.   KEY WORDS: Sodium dodecyl benzene sulfonate, Iron(III) complex, Spectral analysis, TGA, Magnetic properties   Bull.
