The complexes of Co(II), Ni(II) and Cu(II) with 3-hydroxysalicyliden-p-aminoacetophenoneoxime were prepared and characterized by physical, spectral and analytical data. The metal:ligand stoichiometric ratio is 1:2 in all the complexes. It was determined that the bidentate behavior of the ligand is accomplished via the phenolic oxygen and the azomethine nitrogen atoms. The presence of water is revealed by thermograms and supported by the presence of relevant bands in their IR spectra. Suitable structures have been proposed for these complexes.

The novel Schiff base ligand, 4-methoxysalicyliden-p-aminoacetophenoneoxime (LH) was synthesized starting from p-aminoacetophenoneoxime and 4-methoxysalicylaldehyde. Mononuclear cobalt(II), copper(II) and zinc(II) complexes of the ligand have been prepared by using Co(II), Cu(II) and Zn(II) salt with a metal to ligand ratio of 1:2. The structures of the ligand and its complexes were identified by using elemental analyses, IR, 1H- and 13C-NMR spectra, magnetic susceptibility measurements, UV spectra and thermogravimetric analyses (TGA).
