The magnetic behaviour of some polynuclear methoxide complexes of iron(III) with aromatic acids

Abstract

The magnetic susceptibility between 80 and 350 K is reported for FeL(OMe)₂ type complexes of iron(III) where L is aromatic acid. The antiferromagnetism and the single C-O methoxide band at 1038-1052 cm^-1 are interpreted in terms of a planar cluster of four trigonal prismatic iron atoms sharing parallel edges and equivalent, bridging methoxo groups.
