Abstract A novel charge transfer complex (CTC), C 14 H 10 N 2 OS· C 7 H 6 N 2 S was synthesized by the reaction of 2-aminobenzothiazole (ABT) with its derivative Schiff base (2- ((benzo [d] thiazol-2-ylimino) methyl) phenol is abbreviated as BYMBP) in THF. This complex was characterized by 1 HNMR, 13 CNMR, IR and UV–vis. Crystal structure of the complex has been determined by X-ray diffraction. The crystal is triclinic, space group P-1 ...
