Two new novel Cu(II) complexes with versatile azide or thiocayanate bridging derived from symmetrical azo-linked Schiff base of 1-(5-Chloro-2-hydroxy-Phenyl)-Ethanone and propane 1,3-diamine have been properly synthesized. The above two complexes are synthesized by direct reaction of ligand with appropriate concentration of copper metal salts and also the template method. The azo-linked Schiff base ligand and the metal complexes were characterized on the basis of common elemental analysis (C, H and N), and several popular micro analytical techniques like IR, UV-Vis, mass (m/e) spectroscopic study. The Schiff base ligand was further identified by using 1H NMR spectra. Additional magnetic moment data was provided to establish probable geometry of the synthesized complexes. The electronic spectra and magnetic moment data suggests that environment of Cu(II) in the reference complexes must be square pyramidal and square planar. The molar conductivity values indicate that the two newly synthesized copper complexes are totally non-eletrolyte. All the experimental results suggests that Cu(II) metal in both complexes bonded through the imino nitrogen of the respective ligand after proper incorporation of azide or thiocyanate pseudohalides. The copper complexes showed magnetic moment value within the range 1.85-1.88 μB.
