In this paper, synthesis of a novel Schiff base ligand based on bis(2-amino-4-pheny1-5-thiazolyl)disulfide and its corresponding Ni(II) complex was reported. This ligand was prepared through the formation of an imine bond between 2-hydroxy-1-naphthaldehyde and bis(2-amino-4-phenyl-5-thiazol)disulfide in absolute methanol as solvent. The characterizations were performed by FT-IR, H-1 NMR, C-13 NMR, elemental analysis, and single crystal X-ray analysis. In the molecular structure, the ligand possessed anti-conformation around -S-S- bond and monomeric moieties were linked into the chains through the C-Hai-O and pi ai-pi interactions. The reaction of the synthesized ligand with NiCl2 in methanol afforded the corresponding Ni(II) complex. The resulting product was further investigated by thermal gravimetric and differential thermal analysis, which confirmed the formation of desired polymeric complex. The electrochemical behavior and formation of Ni(II) complex in dimethyl sulfoxide (DMSO) solution were investigated by means of cyclic voltammetry and UV-Vis titration, respectively.
