The title complex, [Cu(C13H9Cl2N2O)(NCS)]n, is a novel thiocyanate-bridged polynuclear copper(II) compound. The CuII atom is five-coordinated in a square-pyramidal configuration, with one O and two N atoms of one Schiff base ligand and one terminal N atom of a bridging thiocyanate ligand defining the basal plane, and one terminal S atom of another bridging thiocyanate ligand occupying the axial position. The [2,4-dichloro-6-(pyridin-2-ylmethyliminomethyl)phenolato]copper(II) moieties are linked by the bridging thiocyanate ligands, forming polymeric chains running along the a axis.
