1-(o-Tol-yl)thio-urea.

In the title compound, C(8)H(10)N(2)S, the o-tolyl group and the thio-urea core are planar. The mean planes of the two groups are almost perpendicular [82.19 (8)°]. The thio-urea group is in the thio-amide form, in which resonance is present. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯S hydrogen bonds, forming two infinite chains parallel to the (110) and (10) planes.

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.
