Abstract
In the title compound, C(17)H(21)NO(2)S(2), the coumarin ring system is nearly planar, with a maximum deviation of 0.080 (2) Å from the mean plane. An intra-molecular C-H⋯S hydrogen bond occurs. The crystal structure features C-H⋯S hydrogen bonds and weak π-π inter-actions with a centroid-centroid distance of 3.679 (1) Å.
