title: 1-Methyl-3-phenyl-thio-urea.
abstract: The title compound, C8H10N2S, was prepared by reaction of methyl-amine solution, KOH and phenyl-iso-thio-cyanate in ethanol. It adopts a syn-Me and anti-Ph conformation relative to the C=S double bond. The dihedral angle between the N-C(=S)-N thio-urea and phenyl planes is 67.83 (6)°. In the crystal, the mol-ecules centrosymmetrical dimers by pairs of N(Ph)-H⋯S hydrogen bonds. The dimers are linked by N(Me)-H⋯S hydrogen bonds into layers parallel to (100).
