Nature and Composition of Fe(III) Complexes with Some Polyphenolic Ligands

Abstract

The chelated complexes of Fe(III) of the type FeL3 [where L is the mononegative anion of phloroacetophenone (PHA); 2.4-dimethoxyphloroacetophenone (DMPHA); 4-benzvloxyres-acetophenone (BRP); 2,6-dihydroxyphenylbenzylketone (DHPBK); 2,4,6-trihydroxyphenyl-4′-methoxybenzylketone (THPBK); 2-hydroxy-4,6-dibenzyloxyphenyl-3′,4′-dioxymethylenebenzyl- ketone (HBMK); 2-hydroxy-3-prenyl-4′,6′-dibenzyloxyphenyl-3′,4′-dioxymethylenebenzyl- ketone (HPBMK); naringenin (NG); 2-methyl-5,7-dihydroxychromone (MDHC) and methyl-β-resorcylate (MR)] have been prepared and characterized by elemental, magnetic, infrared and electronic spectral studies.
