摘要	Under solvothermal conditions, one polynuclear Fe-III complex of formula (Fe-3{(Py)C(Ph)O}(4)Cl-4}FeCl4] (1) was synthesized from reaction of phenyl-pyridine-2-yl-methanone oxime (py)C(ph)NOH with FeCl3, and one Fe-II/Fe-III/Fe-II complex of composition [Fe-3{(py)C(ph)NO}(6)][CH3COO] (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 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 anti-ferromagnetic Fe-III center dot center dot center dot Fe-III interactions. Theoretical calculations based on density functional theory were performed using the crystal structure of complex 1. (C) 2012 Elsevier B.V. All rights reserved.
