Abstract

The novel μ-oxo diiron(III) Schiff base complexes, {[Fe(tbusalphn)]2(μ-O)} (1) [tbusalphn = N,N′-o-pheny-lenebis(3,5-di-tert-butylsalicylideneiminato)] and {[Fe(R,R-salchxn)]2(μ-O)}(2) [R,R-salchxn = N,N′-R,R-cyclo-hexanebis(salicylideneiminato)] have been synthesized and characterized by elemental analyses, spectroscopy, magnetic susceptibility, electrochemical measurements and X-ray diffraction techniques. X-ray analyses revealed that the complex 1·CH3OH has nearly linear Fe-O-Fe angle of 176.5(2)° due to their steric crowding of ligands owing bulky substitute group, while fairly bent Fe-O-Fe angle was allowed by the reduced steric crowding of the ligands in 2·C4H6N2·0.5C2H5OH [149.6(1)°]. FT-IR, UV-Vis, CD spectra, magnetic susceptibility and cyclic voltammogram (CV) of complexes 1 and 2 have been further investigated.
