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

The title compound, [Cu(C16H19N2O)(N3)], 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 CuII 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.
