摘要

By the reaction of the tetradentate Schiff base ligand H_2salbn, N,N'-disalicyclidene-1,4-diaminobutane with Fe~(III)Cl_3·6H_2O in the presence of Et_3N in MeOH a dinuclear iron(III) complex, [Fe~(III)(salbn)(mu-OMe)]_2 (1), has been obtained, whereas in EtOH, dinuclear complexes, [Fe~(III)(mu-salbn)]_2(mu-O) (2) and [Fe~(III)(salbn)]_2 (mu-salbn) (3), are obtained. The structure of the complex 1 consists of two Fe(III) centers one tetradentate salbn ligand (N_2O_2) which aer bridged by two methoxo groups to yield a planar Fe_2O_2 core. On the other hand, in the complex 2, each of the two Fe(III) ions has a five-coordinate structure in which both salbn ligands act as a bridging didentate ligand and one oxygen atom bridges two Fe(III) ions to form a mu-oxo structure. The structure of the complex 3, which was obtained by accompanying with complex 2, consists of two six-coordinate Fe(III) centers in which each Fe(III) ion is coordinated by a tetradentate salbn ligand (N_2O_2) and one bridging salbn ligand (NO).
