Azido{1-[2-(propylamino)ethyliminomethyl]naphthalen-2-olato}copper(II)

The title compound, [Cu(C16H19N2O)(N-3)], was synthesized by the reaction of equimolar quantities of 2-hydroxy-1-naphthaldehyde, N-propylethane-1,2-diamine, sodium azide and copper(II) acetate in a methanol solution. The Cu-II ion in the compound is four-coordinated by one imine N, one amine N, and one phenolate O atoms of the Schiff base ligand 1-[2(propylamino)ethyliminomethyl]naphthalen-2-ol and by one terminal N atom of an azide anion, forming a square-planar coordination. The propyl group and attached NH are disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.
