The Synthesis of Two New Isonitrosoacetophenone Derivatives and Investigation of Their Ni(II), Co(II), Cu(II), and Zr(IV) Complexes

In the present study, two new ligands, 4-chlorobenzal-azino-isonitrosoacetophenone (L-1), 4-methylbenzal-azino-isonitrosoacetophenone (L-2) and their metal complexes were synthesized using acetophenone as a starting material. The coloured complexes were prepared by the addition of chloride salts of Ni(II), Co(II), Cu(II) and Zr(IV) ions to a solution of ligands. In conclusion, the structures of the obtained ligands and their complexes were characterized by FT-IR, and H-1 NMR spectra, AAS (atomic absorption spectrum) analysis, magnetic susceptibilities as well as elemental analysis.
