(E)-5-tert-Butyl-1-cinnamoylthio­biuret

The title compound, C15H19N3O2S, is one of the thio­urea herbicides in which 1-tert-butyl­urea replaces 4,6-disubstituted pyrimidine. The crystal structure reveals intra­molecular N—H⋯O and N—H⋯S hydrogen bonds that form six-membered rings, whereas inter­molecular N—H⋯O hydrogen bonds connect mol­ecules along the b axis.
