Schiff bases and complexes of copper with Schiff base considered as a very important class of organic compound which have wide applications in biology. In this work, three series of new Cu (II) complexes with some new Schiff base ligands have been reported. Formula of synthesized complexes is [CuL₂]²⁺, where "L" is schiff base formed by condensation of Isonicotinic acid hydrazide and different Aril aldehyes have been prepared. The coordition takes place through the nitrogen and oxygen groups.All of these ligands and complexes are characterized by FT-IR, UV-Vis,¹H-NMR spectroscopy and thermal gravitation analysis (TG, DTA) methods.
