The new dinuclear Fe(III) complex was synthesized by reaction of FeCl3.6H2O with potassium pyridoxylidenglycinate in ethanol-water solution. Pentadentate pyridoxal Schiff base ligand was generated by aldol condensation of potassium pyridoxylidenglycinate and pyridoxal. The complex was characterized by X-ray structural analysis, elemental analysis, spectral and magnetic measurements. Structural analysis showed that each Fe(III) center has a distorted octahedral FeNO5 core, which is sixfold coordinated through iminic nitrogen atom, two phenoxido oxygen atoms, alkoxo oxygen atom and carboxylato oxyg en atom from two Schiffbase ligands forming a rhombic arrangement of metal ions and oxygen atoms
