Abstract

A series of mononuclear iron (III) complexes of the type [Fe (L) Cl3], where L is a systematically modified N2O or N3O ligand with a methoxyethyl/tetrahydrofuryl ether oxygen donor atom, have been isolated and studied as models for catechol dioxygenases. The X- ray crystal structures of [Fe (L2) Cl3] 2,[Fe (L6) Cl3] 6,[Fe (L5)(TCC) Cl] 5a, where H2TCC= tetrachlorocatechol,[Fe (L6)(TCC) Br] 6a, and the μ-oxo dimer [{Fe (L6) Cl} 2O](ClO4) 26b ...
