N-Propionylthio-urea

The mol-ecule of the title compound, C(4)H(8)N(2)OS, is essentially planar; it adopts a trans configuration with respect to the position of the propionyl group relative to the thiono S atom about the C-N bond. The mol-ecular structure is stabilized by an intra-molecular N-H⋯O hydrogen bond between the propionyl O atom and the amide H atom. Mol-ecules are linked into a two-dimensional network parallel to the (10) plane by N-H⋯O and N-H⋯S inter-molecular hydrogen bonds.
