Abstract :
Three new Cu(II) complexes of the type [Cu(phen-dione)(L)](NO3)2 (1), [Cu (opd) (L)](NO3)2 (2) and [Cu(dpa)(L)](NO3)2 (3) that phen-dione= 1,10-phenanthroline-5,6-dione, opd=ortho-phenylenediamine, dpa=2,2´dipyridilamine and L=2-hydroxyacetophenone4-hydroxybenzoicacidhydrazone have been synthesized and characterized using the IR, UV-Vis, 1H-NMR spectroscopies and cyclic voltammetery method. The effective magnetic moment (?eff) of paramagnetic complex (3) was consistent with the spin only values for mononuclear d9 copper (II) systems. The FT-IR results showed that the H2L ligand adduct to metal center as a tridentate ligand by nitrogen and oxygen atoms. Electrochemical data for all complexes showed quasi-reversible reduction process for ligands and copper ions in DMF solution. Also ligand center transition, ligand field and charge transfer (LMCT) bands have been observed in the synthesized complexes.
