Abstract
A new ferric ephedrine complex, [Fe(eph)(2)(Cl)(2)]center dot ClH2O, was prepared. The chelating behavior of the ephedrine drug towards ferric(III) ions was discussed upon infrared, solid reflectance and Mossbauer spectroscopy. Ephedrine has two powerful donating sites -OH and -NH groups, so it is prefer to acts as bidentate ligand. The electronic spectra as well as the magnetic susceptibility measurements are speculate with each other the actual geometry. The Mossbauer spectral analysis are used as confirmatory tool for supporting the geometrical environment of Fe(III) complex. The thermal analysis TG/DTG/DSC is an important tool led to calculate the amount of solvent molecules inside or outside of coordination sphere also make follow-up for the stability of the prepared complex. The spectral and thermal analyses are supporting the coordination of the eph ligand in its neutral state. The Coats-Redfern relations were carried out to calculate the thermodynamic parameters for ferric complex.
