A dinuclear oxygen-bridged Schiff base iron(III) complex derived fromN,N′-bis(2-hydroxybenzylidene)-1,2-diaminopropane

Abstract

The title compound, μ-oxo-bis({2,2-[propane-1,2-diyl­bis­(nitrilo­methyl­idyne)]diphenolato}iron(III)), [Fe2(C17H16N2O2)2O], is an unusual dinuclear iron(III) complex. Each FeIII ion has a distorted square-pyramidal coordination geometry. In the basal plane, the Fe atom is coordinated by two N atoms and two O atoms of the Schiff base ligand. The apical position is occupied by a bridging O2− ion, which links to the other FeIII ion in the complex. In the crystal structure, pairs of dinuclear iron(III) units form dimers by way of a pair of intermolecular C—H⋯O interactions. The dimers stack along the a axis and there are no other short intermolecular contacts.
