摘要：

Three new Fe-III complexes have been synthesized with the tridentate ligand salEen (salEen = N-ethyl-N-(2-aminoethyl)salicylaldiminate). Two of them are neutral dinuclear complexes and their structures have been resolved. Their formulae are [Fe(salEen)(Cl)(mu-CH3O)](2) and [Fe(salEen)(DBC)](2) (DBC = 3,5 di-tert-butylcatecholate), respectively. These complexes exhibit a 'diamond-core' geometry with the ferric ions antiferromagnetically coupled by the bridging oxygens of the methoxy or DBC ligands, respectively. The last complex is a mononuclear one of formula [Fe(HsalEen)(2)Cl-2]Cl, with the protonated ligand acting as a bidentate one. This compound is actually a mixture of two complexes with the same formula but with different coordination of the HsalEen fragments. (C) 2003 Elsevier B.V. All rights reserved.
