3-Acetyl-1-phenyl-thio-urea.

In the crystal structure of title compound, C(9)H(10)N(2)OS, there are two symmetry-independent mol-ecules, each having an intra-molecular N-H⋯O hydrogen bond generating an S(6) ring motif. The benzene rings and the virtually planar acetyl-thoiurea fragments [r.m.s. deviations = 0.0045 and 0.0341†à ] are oriented at dihedral angles of 50.71†(6) and 62.79†(6)° in the two mol-ecules. In the crystal, N-H⋯S and N-H⋯O hydrogen bonds link mol-ecules via cyclic R(2) (2)(8) and R(2) (2)(12) motifs into a one-dimensional polymeric network extending along [101]. The intra- and inter-molecular N-H⋯O inter-actions are part of a three-center hydrogen bond. A C-H⋯S inter-action also occurs.
