Synthesis and Kinetics Study of Copper(II) Complex Formation Reaction with N, N'-bis(salicylidene)- 1,2-ethylenediamine Ligand

Abstract

This paper includes the preparation of copper (II) complex of Schiff base N, N'-bis (salicylidene)
ethylenediamine, which known as (Salen). This complex was characterized by elemental analysis, mass
spectrometry, infrared spectrum, ultraviolet spectrum, in addition to magnetic sensitivity measurement. It was
found that the complex possesses the formula [Cu (Salen)], which is associated with the copper (II) ion with
two azomethene nitrogen atoms and two phenolic oxygen atoms of the Salen ligand. The kinetics of the
complex formation reaction were also studied using a UV-visible spectrophotometer in
dimethylsulfoxide(DMSO) solvent at temperatures 30, 40 and 50 ℃ under the pseudo-first order reaction
conditions.
