Abstract:
Binary and ternary complex formation equilibria of M(II) with SAH-hydrazone ligand (2-((2-phthalazin-1-yl)hydrazono)methyl)phenol) in nearness of phenylalanine (Phe) as an agent case of amino acids have been examined utilizing the pH-metric titrations. The relative concentrations (M: L: X=1:2:2, 1:2:4, 1:4:2) and stabilities of the ternary species are contrasted and those of binary species. The AM-B type complexes were shaped, where Aspartic corrosive utilized as essential ligand and Cytosine optional ligand, delineated as An and B separately arrange with metal M (II) were exclusively controlled by the basicity of the carboxyl or amine gathering. Moreover, the impact of temperature on protonation of ligands and formation of blended ligand complexes (M-SAHPhe) was investigated. The thermodynamics were calculated and talked about.
