Abstract

In the present work, the proceeding ligand as well as its complexes have been studied, through the studying of effects of the temperature that ranges from (25o to 45oC) and a variety of the concentrations on molar conductivity values from Arinus' law application. The limiting molar conductivity of Ligand (L) and [M(L)2Cl]Cl.H2O complex in different temperature was measured, by which decomposition constant and uniform molar conductivity are determined, thermo-dynamic parameters (i.e. ΔH, ΔG and ΔS) had been estimated then discussed. Results have shown that the value of the molar conductivity is increased with the increase of the temperature and decreased with the increase of the concentration by using DMSO solvent. The process of the dissociation is an exothermic process for the complex (M+2 = cu), in addition to that, characterizing this prepared complex has been carried out through measuring the value of the melting point, FTIR spectra, UV-Visible spectra, and the measurements of the magnetic susceptibility, and later in comparison to the ligand and metal solutions.
