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 (L₁), 4-methylbenzal-azino-isonitrosoacetophenone (L₂) 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 ¹H NMR spectra, AAS (atomic absorption spectrum) analysis, magnetic susceptibilities as well as elemental analysis.
