Under solvothermal conditions, one polynuclear Fe III complex of formula [Fe 3{(py)C(ph)O} 4Cl 4][FeCl 4] (1) was synthesized from reaction of phenyl-pyridine-2-yl-methanone oxime (py)C(ph)NOH with FeCl 3, and one Fe II/Fe III/Fe II complex of composition [Fe 3{(py)C(ph) NO} 6][CH 3COO] (2) was prepared from treatment of (py)C(ph)NOH with Fe(OAc) 2. The most interesting synthetic feature of complex 1 is the in situ transformation of (py)C(ph)NOH into the (py)C(ph)O - ligand. Complexes 1 and 2 were characterized by X-ray single crystal diffraction, IR spectroscopy, and elemental analysis. X-ray analysis revealed that complex 1 contains a V-shaped Fe III core with two terminal Fe III atoms displaying distorted square-pyramidal geometries and one central Fe III ion exhibiting octahedron geometry. Complex 2 is a mixed-valence linear Fe II/Fe III/Fe II complex with all the three metal centers displaying distorted octahedron geometries. The low-temperature magnetic susceptibility measurement for the solid sample of 1 revealed the weak antiferromagnetic Fe III..Fe III interactions. Theoretical calculations based on density functional theory were performed using the crystal structure of complex 1.
