The 1-diethanolamino-2-nitrilo-carboethoxyethane and quinoxaline-phenylohydrazone compounds as well as their Cu(II) complexes have been prepared and investigated using elemental analysis, IR, UV-VIS and EPR methods. A chemical structure for these compounds based on elemental analysis and IR data has been proposed. EPR spectra of Cu(II) ions in essentially axial and orthorhombic symmetry have been observed for the two Cu(II) complexes. The results are interpreted in terms of ligand field theory and comparison is made with the proposed chemical structures. The temperature dependence of the EPR spectra revealed that the second compound decomposes abruptly at the melting point in contrast to the first one where gradual decomposition occurs. Key words: complexes, synthesis, IR, EPR, ligand field theory
