Synthesis, crystal structures and magnetic studies of dicyanamide bridged two new 1D copper(II) complexes

Two new dicyanamide bridged 1D polynuclear copper(II) complexes of a hydrazone and a Schiff base ligand have been synthesised and structures of both the complexes and their crystal packing arrangements have been established by X-ray crystallography. Variable temperature magnetic susceptibility measurement studies indicate weak antiferromagnetic interaction operates among the copper(II) centres in both 1 (J = −0.10 cm−1) and 2 (J = −1.41 cm−1).
