High-Spin Iron(III) Complex with 2-(2-Imidazolyl)phenolate

Abstract

The crystal structure of tris{2-(2-imidazolyl)phenolato}iron(III), which was synthesized by a reaction of Fe(BF4)2•6H2O and 2-(2-imidazolyl)phenolate in methanol, was determined by X-ray crystallography. The compound crystallized in the trigonal space group R-3 and Z = 6 with cell parameters a = 15.830(3)Å, c = 19.973(4)Å, V = 4334.4(18)Å 3 . The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0385 and 0.1005, respectively, for all 2337 independent reflections. The iron atom is coordinated by three 2-(2-imdazolyl)phenolato ligands in a facial N3O3 configuration, where the solvent methanol molecules are hydrogen-bonded to the phenolato-oxygen atoms.
