Abstract
Abstract A new tetradentate N 2 S 2 Schiff base ligand derived from 5-bromothiophene-2-carbaldehyde and its [CuBr(N 2 S 2 )]Br complex were synthesized in good yield. FT-IR was investigated to monitor the condensation reaction during the ligand synthesis process. The ligand, N 2 S 2 , and its complex, [CuBr(N 2 S 2 )]Br, complex have been characterized with the aid of several spectroscopic techniques such as UV–vis., MS, FT-IR, EA, EDS, NMR (for N 2 S 2 ), as well as by thermal (TG/DTG) analysis. In addition, cyclic voltammetry has been employed to examine the redox behavior of [CuBr(N 2 S 2 )]Br complex in N,N’-dimethylformamide (DMF) containing 0.10 M tetra- n -butylammonium perchlorate (TBAP). The anti-conformation EE isomer of the ligand (N 2 S 2 ) was confirmed by means of X-ray crystallography; ligand crystallizes in to the monoclinic P 2 1 / c space group. N 2 S 2 ligand was subjected to DFT-theoretical calculations and results are consistent with the experimental chemical analysis.
