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).Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
