| Abstract: Eight novel binuclear tetradentate Schiff base complexes (M=Cu(Ⅱ),Ni(Ⅱ),Zn(Ⅱ)) are synthesized. The structure of complexes is two discrete Schiff base unit bridged. The complexes were condensed from series sub-stituent Ketones (5-chloro-2-hydroxybenzophenone, 5-methyl-2-hydroxy-benzophenone, 5-Bromo-2-hydroxybenzop- henone) and dialdehydes (5,5′-methylene-disalicylaldehyde) with the amino group of 1,2-diaminobenzene, and by Metal ion as template. The compounds were characterized by elemental analyses, FT-infrared spectra, Raman, 1H NMR, UV-vis electronic spectra, EPR spectra. The FT-infrared spectra and Raman spectra of complexes were compared and discussed. The UV-vis election spectra, 1H NMR and EPR spectra of complexes have also been attributed and minutely analyzed. |
