Abstract

Synthesis and Characterization of New Vic-dioximes and Their Nickel Complexes

In this study, four new vic-dioximes, anti-4-aminodiphenylaminoglyoxime (H₂L¹), anti-4-aminodiphenylaminophenylglyoxime (H₂L²), anti-3-hydroxy-5-sulpho-2-naphthylaminoglyoxime (H₃L³), and anti-3-hydroxy-5-sulpho-2-naphthylaminophenylglyoxime (H₃L⁴), as well as their nickel complexes, were synthesized. The structures of these new compounds (both the ligands and complexes) were characterized by the following methods: IR, NMR, atomic absorption spectroscopy, elemental analysis, differential thermal analysis (DTA), and thermogravimetric analysis(TGA).
