Abstract

In the current research work, the prepared new ligand 3hydroxy-2-(3-(4-nitro-benzoyl) thiouriedo) propanoic acid (NTP) has undergone synthesis through the reactions of 4-nitrobenzol isothiocyanate with the serine amino acid; its complex has been studied by effects of the temperature ranging within (25-45 ^oC) and various concentrations on molar conductivity values from Arinus' law application, by which decomposition constant and uniform molar conductivity is determined. The thermo0dynamic parameters (i.e., ΔS, ΔG, and ΔH) have been estimated and then discussed. Results have shown that the level of the molar conductivity increases with the degree of temperature and decreases with the increase of the concentration using solvent (DMSO). The dissociation process is exothermic; that ligand's transition metal complex has been synthesized and then characterized through the UV-Vis spectra, FTIR, conductivity measures, and magnetic susceptibility. The general formula [M(NTP)2], M⁺²= (Cu), is that the molecular form for those complexes is tetrahedral, except that the copper is of a square planer.
