Synthesis, Characterization and Cyclic Voltammetry Study of 5-(2-((7-Methoxynaphthalen-2-yl)Methylene)Hydrazineyl)-1,3,4-Thiadiazole-2-Thiol and its Metal Complexes

The current research included synthesis new Ligand5-(2-((7-methoxynaphthalen-2-yl)methylene) hydrazineyl)-1,3,4-thiadiazole-2-thio(L).the various metal ion complexes ofCr(III), Fe(II),Ni(II)andCo(II) were synthesized. Spectral methods were used to characterize the Ligand and its complexes spectra techniques including , 1H-NMR ,13C-NMR Mass spectraand molar conductivity.Cyclovoltametry was used to study the oxidation-reduction processes (electrochemical properties) of both the Ligand and its complexes, providing further evidence for complex formation.The semi-empirical calculation using Hyperchem software to obtain the optimization molecular structure of the Ligand and its complexes, and to perform theoretical calculations to study the electrostatic potential. This provided information on suitable complexation sites and possible complex shapes by theoretically studying the energy of these complexes and using molar conductivity calculations., Based on the results obtained from spectral and theoretical methods, we propose octahedral geometrics for Cr (III), Fe (II) ,Ni (II) and Co(II).
