Abstract: Complexes of iron(III) with ethylene glycol and 3(2’ -hydroxyphenyl)-5-(4’ -substituted phenyl) pyrazolines, [Fe(OCH2CH2O)(C15H12N2OX)]mnH2O and [Fe(C15H12N2OX)2(OCH2CH2OH)] (where OCH2CH2O and OCH2CH2OH = ethylene glycol moiety; C15H12N2OX = 3(2’ -hydroxyphenyl)-5-(4-X-phenyl)pyrazoline; X = H, CH3, OCH3, or Cl; m = 2-3 and n = 2-3) have been synthesized and characterized by elemental analysis (C, H, N, Cl, and Fe), molecular weight measurement, magnetic moment data, thermogravimetric analysis, molar conductance, spectral (UV-Vis, IR, and FAB mass), scanning electron microscopy, and X-ray diffraction studies. Bonding of ethylene glycol and pyrazolines in these complexes and the particle size of iron(III) complexes are discussed. Antibacterial and antifungal potential of free pyrazoline and some iron(III) complexes are also discussed.
