A new dinuclear Fe(III) complex, [Fe2(bp)2(N3)2] CH3OH (1), was synthesized by the reaction of FeCl2·4H2O, NaN3 and H2bp in methanol where H2bp is the bis(phenolate) ligand obtained from the Mannich condensation of 4-fluorophenol, formaldehyde and 2-(aminomethyl)pyridine. The ligand was characterized by spectroscopic methods (NMR, FT-IR, UV–Vis) and elemental analysis. Complex 1 was characterized by spectroscopic methods, elemental analysis and single crystal X-ray diffraction analysis. X-ray studies revealed that complex 1 is a centrosymmetric phenolate bridged dinuclear Fe(III) complex in which the Fe(III) ions have a distorted octahedral coordination environment. The complex was further studied by TGA analysis and magnetic measurements. Magnetic studies indicated that the bis(phenolate) bridging ligand mediates an antiferromagnetic interaction between the Fe(III) ions with J = −7.3 cm−1, H = -2JS1S2.
