A dinuclear oxygen-bridged schiff base iron(ııı) complex derived from n,n'-bis(4-methoxy-2-hydroxybenzylıdene)2,2-dimethylpropane-1,3-diamine

Abstract

The mu-oxo-bridged Fe(III) dimer complex [{Fe(4-MeOL1)}(2)(mu-O)]center dot HOCH3, (H-2-4-MeOL1 = N,N'-bis(4-methoxy- 2-hydroxybenzylidene)-2,2-dimethylpropane-1,3-diamine), 1 is synthesized and characterized by single crystal X-ray diffraction. Complex 1 contains a [{Fe(4-MeOL1)}(2)(mu-O)] dimeric unit with a methanol solvent molecule of crystallization. Each Fe(III) ion has a distorted square-pyramidal coordination geometry. In the basal plane, the Fe(III) atom is coordinated by two N and two O atoms of the Schiff base ligand. The apical position is occupied by a bridging O2- ion, linking another Fe(III) ion in the complex. There are intermolecular C-H. O and C-H....pi interactions among the dinuclear complexes.
