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

Abstract

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.
