Synthesis and characterization of a new ligand (E)-2-(4-((2-(2-((2- hydroxynaphthalen-1-yl) methylene) hydrazinyl) thiazol-4-yl) amino) phenyl) acetic acid, and its complexes

Abstract

In this research, a new heterocyclic compound (E)-2-(4-((2-(2-((2-hydroxynaphthalen-1-yl) methylene) hydrazinyl) thiazol-4-yl) amino) phenyl) acetic acid was synthesized from the reaction of 2-hydroxynaphthalene-1-carbaldehyde with 2-(4-((2-hydrazinylthiazol-4- yl)amino)phenyl)acetic acid. This compound was utilized as the ligand (HL) to synthesize series of complexes by its reaction with some metals elements salts (cobalt chloride hexahydrate, nickel chloride hexahydrate, copper chloride dihydrate and anhydrous zinc chloride). The ligand was characterized using different types of analytical techniques such as FT-IR, 1H-NMR, mass spectrum and UV-Vis. Spectrum. The complexes were characterized by using UV-Vis- spectrum, LC.-MS. technique, FT-IR spectrophotometer, conductivity measurements, magnetic susceptibility and atomic absorption. The results of the analysis revealed that the final structures of the complexes are octahedral.
