Abstract
In the title molecule, C13H14N2O2S, the dihedral angle between the pyrazine and benzene ring planes is 2.21 (5)°. The mean plane of the quinoxaline ring system is inclined to the sufanylacetate substituent by 81.74 (2)°. In the crystal, inversion-related C—H...N hydrogen bonds form dimers, which are linked into oblique stacks along thea-axis direction by C—H...O hydrogen bonds and π–π-stacking interactions.
