Ethyl 2-(3-phenyl­thio­ureido)-5,6-di­hydro-4H-cyclo­penta­[b]thio­phene-3-carboxyl­ate

In the title compound, C₁₇H₁₈N₂O₂S₂, the angle between the mean plane defined by the atoms of the 5,6-dihydro-4H-cyclo­penta­[b]thio­phene moiety (r.m.s. deviation = 0.19 Å) and the phenyl ring is 72.8°(2). The mol­ecular conformation is stabilized by an intra­molecular N—H...O inter­action, which generates an S(6) ring motif. In the crystal, pairs of N—H...S hydrogen bonds link the mol­ecules to form inversion dimers with an R₂²(8) ring motif.
