Abstract

A series of new compounds including 2-({[(4-(propoan-2-yl)benzyl]Oxy}methyl)tetrahydrofuran ligand were tested in order to link auxiliary and labile ligands to iron arene complexes. The given reaction of benzyletherfurane ligand with Fe (II) sources resulted to the isolation of unexpected mixed valence µ3-oxo-Fe6IIFeIII compound, which has been fully characterized by x-ray crystallography. The resulting complex differs from the similar compound known in the literature.
 
Key words: Mixed valence complex, heptanuclear Fe(II,III), wheel motif structure, dangling spatial orientation of furfuryl ligand, 2-({[4-(propoan-2-yl)benzyl]Oxy}methyl)tetrahydrofuran, single crystal.
