The title compound, C22H18N4O2S2, was characterized by 1H and 13C NMR, solid-state IR spectroscopy and X-ray crystallographic techniques. The crystal structure determination reveals that the twisting modes of the two side arms are different [C-N-C-O and C-N-C-N torsion angles = -1.2 (3) and 1.1 (3)°, respectively, in one arm and 24.1 (3) and -5.1 (3)°, respectively, in the other]. The crystal structure involves N-HO and N-HS hydrogen bonds.
