Synthesis of New Glyoxime Derivatives,Characterization and Investigation of Their Complexes with Co(II),Ni(II),and Cu(II) Metals and Thermal Studies

摘要

In this study,two new vic-dioxime ligands and their complexes with Co~(2+),Ni~(2+),and Cu~(2+) ions were synthesized.Secondary amines (morpholine and piperidine) reacted with anri-chloroglyoxime to give morpho-lineglyoxime (H_2L~1) and piperidineglyoxime (H_2L~2) ligands.All the complexes have a metal to ligand ratio of 1 ;2.The structure of the ligands and their complexes was proposed from elemental analyses,IR,UV-VIS,~1H and ~(13)C NMR spectra,conductivity,magnetic susceptibility measurements,and thermogravimetric analyses.
