4-Carbethoxy-1-[4-(N,N-dimethylamino)benzoyl]thiosemicarbazide

Abstract

The molecular structure of the title compound, C13H 18N4O3S, (systematic name: ethyl N-{2-[4-(dimethylamino)benzoyl]hydrazinethiocarbonyl}carbamate) is stabilized by intramolecular N - H⋯O=C hydrogen bonding arranged in an S(6) graphset motif. In the crystal, inversion dimers connected via intermolecular N - H⋯S=C hydrogen bonds [R 2 2(8) graphset motif] form sheets parallel to the ( 21) plane. Dimers are also formed by the molecules via weak intermolecular N - H⋯S=C hydrogen bonds [R 2 2(10) graphset motif] connecting the sheets. © 2010.
