摘要:
Iron(III) complexes of the Schiff base N,N'-bis(4-antipyrylmethylidene)ethylenediamine (BAME) having the general formulae [Fe(BAME)(2)X]X-2 (X=ClO4 or NO3) and [Fe(BAME)(2)X-2]X (X=SCN, Cl or Br) have been s+ynthesized and characterized by elemental analyses, electrical conductance in non-aqueous solvents, infrared and electronic spectra, and magnetic. susceptibility measurements. In these complexes, BAME acts as a neutral bidentate ligand coordinating through both azomethine nitrogen atoms. In the perchlorate and nitrate complexes, one of the anions is bidentate while in the thiocynate complex, two of the anions are bound in a monodentate fashion to the metal ion. In the chloride and bromide: complexes, two of the halide ions are coordinated. A high-spin octahedral geometry is assigned around Fe(III) in all of these complexes.
