N-Propionylthio­urea

The mol­ecule 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 mol­ecular structure is stabilized by an intra­molecular N—H⋯O hydrogen bond between the propionyl O atom and the amide H atom. Mol­ecules are linked into a two-dimensional network parallel to the (10[Image: see text]) plane by N—H⋯O and N—H⋯S inter­molecular hydrogen bonds.
