Ethyl (4-{[(diethylcarbamothioyl)sulfanyl]methyl}-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 Å). 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...

Summary:In the title compound, C18H22N2O4S2, the 2H-chromene ring system is essentially planar (r.m.s. deviation = 0.012 Å). 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) Å].
