THE COORDINATION OF Cu(II) AND THERMAL STUDIES ON SOME QUINOXALINONE DERIVATIVE COMPOUNDS

Abstract

The chelates of Cu(II) ion with some quinoxalinone compounds have been prepared and characterized by elemental analysis, IR, UV-Vis, magnetic susceptibility and TGA. It is shown that the ligands behave as bi- or tridentate ligands with the coordination of one or two chloride atoms in most of the complexes. The thermal decomposition of the compounds has been used to confirm structural information.

Keywords:

• Cu(II) ion
