Abstract

Six new Cu(II), Ni(II) and Co(II) macroacyclic Schiff base complexes [MII(H2L)](ClO4)2 (L = L1 and L2) (I–VI) were prepared by the reaction of two new N2O4 Schiff base ligands in equemolar ratios. The ligands H2L1 and H2L2 were synthesized by reaction of 2-[2-(2-formyl phenoxy)ethoxy]benzaldehyde (A1) and/or 2-[2-(3-formylphenoxy)propoxy]benzaldehyde (A2) and ethanol amine and characterized with IR and 1H, 13C NMR spectroscopy. All complexes were characterized by microanalysis, IR and mass spectrometry, whereas complex I was also characterized by single crystal X-ray (CIF file CCDC no. 1020055). The X-ray structure of complex I revealed that all nitrogen and oxygen atoms of ligand (N2O4) have coordinated to the metal ion. However, Cu2+ ion is in six coordination environment that can bedescribed as a distorted octahedral geometry.
