Abstract Spectroscopic (IR, UV-VIS, Mass, 1HNMR, 13C-NMR and ESR spectra) and elemental studies of the compounds were reported. The magnetic properties and thermal analyses (DTA and TGA) were also carried out. The IR spectra of the prepared compounds suggested that, the compounds adopted either a bidentate or a tetradentate fashion, bonding to the metal ion. Electronic spectra and magnetic susceptibility measurements revealed an octahedral geometry for all metal compounds. The elemental analyses and mass spectral data have justified the composition of the compounds. The ESR spectra of Cu(II) compounds (13), (19) and (20), showed an axial type (dx2-y2) ground state with a covalent bond character and also support the suggested structures of compounds. |
