Studies on Mononuclear Chelates Derived from Substituted Schiff Bases Ligands (Part 8): Synthesis and Characterization of a New 5-Chlorosalicyliden-p-aminoacetophenoneoxime and Its Complexes with Co(II), Ni(II), Cu(II) and Zn(II)

Co(L)2, Ni(L)2, Cu(L)2 and Zn(L)2 were synthesized from p-aminoacetophenoneoxime and 5-chlorosalicylaldehyde and Co(AcO)2.4H2O or Ni(AcO)2.4H2O or Cu(AcO)2.H2O or Zn(AcO)2.2H2O in 1:2 molar ratio, employing a template approach. Based on elemental analyses, molar conductivity and magnetic susceptibility data, IR, 1H- and 13C-NMR and UV spectra, as well as thermal analyses (TG), a tetrahedral geometry for the complexes was determined. The data show that the ligand coordinates to the metal ion via -C=N- and -C-O- groups. All complexes are soluble in common organic solvents such as DMF and DMSO.
