catena-Poly[[{4-bromo-2-[2-(dimethylamino)ethyliminomethyl]phenolato}copper(II)]-μ-azido]

Abstract

The title complex, [Cu(C11H14BrN2O)(N3)]n, is an interesting azide-bridged polynuclear copper(II) compound. The Cu(II) atom is five-coordinated in a square-pyramidal configuration, with one O and two N atoms of one Schiff base and one terminal N atom of a bridging azide ligand defining the basal plane, and another terminal N atom of another bridging azide ligand occupying the axial position. The {4-bromo-2-[2-(dimethylamino)ethyliminomethyl]phenolato}copper(II) moieties are linked by the bridging azide ligands, forming polymeric chains running along the b axis. Adjacent chains are further linked by weak Br...Br interactions into a sheet.
