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

In this study, two new vic-dioxime ligands and their complexes with Co²⁺, Ni²⁺, and Cu²⁺ ions were synthesized. Secondary amines (morpholine and piperidine) reacted with anti-chloroglyoxime to give morpholineglyoxime (H₂L¹) and piperidineglyoxime (H₂L²) 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 ¹³C NMR spectra, conductivity, magnetic susceptibility measurements, and thermogravimetric analyses.__________From Koordinatsionnaya Khimiya, Vol. 31, No. 7, 2005, pp. 535–539.Original English Text Copyright © 2005 by Ozkan, Canpolat, Kaya.The text was submitted by the authors in English.
