Ethyl (4-{[(di-ethyl-carbamo-thio-yl)sulfan-yl]meth-yl}-2-oxo-2H-chromen-7-yl)carbamate.

In the title compound, C18H22N2O4S2, the 2H-chromene ring system is essentially planar (r.m.s. deviation = 0.012 A). The mol­ecular conformation is stabilized by a C—H⋯O hydrogen bond. In the crystal, N—H⋯S and C—H⋯O hydrogen bonds occur, the former enclosing an R22(22) ring motif, and lead to the formation of a two-dimensional slab-like network lying parallel to (10-1). π–π inter­actions are observed between inversion-related aromatic rings [shortest centroid–centroid distance = 3.6300 (11) A].
