The Schiff base ligands and their corresponding metal complexes have expanded enormously and include a vast area of organometallic compounds and various aspects of bioinorganic chemistry [1]. On the other hand, azo compounds are very important molecules and have attracted much attention in both academic and applied research [2]. The azo compounds and their metal-azo complexes are extremely used in dyes and data storage [3]. In this paper, a new complex of Cu(II) and the title Schiff base as a ligand is reported. Elemental, and spectroscopic measurements are used to elucidate the structure of the prepared metal complex. The azo-dye Schiff base behaves as a di-negative N₂O₂ tetradentate ligand. The structure of metal complex is square planar. The azo-dye Schiff base and its complex is characterized by FTIR, DRS, EDAX and thermal analysis methods.
