[FeLX]Y [L = N,N'-ethylenebis(salicylimine) (salen), N,N'-ethylenebis(acetylacetonylimine) (acen), or N,N'-ethylenebis(3-methyloxysalicylimine) (vanen); X = imidazole or N-methylimidazole; Y = BF, ClO, or BPh] compounds have been prepared and studied by means of EPR and magnetic susceptibility measurements at 5-300 K. It has been shown that the different electron-donating properties of acen and salen planar ligands result in different spin states of Fe(III) ions. Intermolecular π-interactions of the outer-sphere BPh ion affect the complexes spin state as well. [ABSTRACT FROM AUTHOR]
