Studies on Mononuclear Chelates Derived from Substituted Schiff Base Ligands(Part 4):Synthesis and Characterization of a New 5-Hydroxysalicyliden-P-Aminoacetophenoneoxime and Its Complexes with Co(II),Ni(II),Cu(II)and Zn(II)

摘要

5-Hydroxysalicyliden-p-aminoacetophenoneoxime(LH)was synthesized starting from p-aminoacetop-henoneoxime and 5-hydroxysalicylaldehyde.Complexes of this ligand with Co~(+2),Ni~(+2),Cu~(+2)and Zn~(+2)salts were prepared.With this ligand,complexes were synthesized using Co~(+2),Ni~(+2),Cu~(+2)and Zn~(+2)salt with a metal:ligand ratio of 1:2.Their structures were elucidated on the basis of elemental analyses,IR,1H-and ~(13)C-NMR,electronic spectra,magnetic susceptibility measurements,molar conductivity and thermogravimetric analyses.
