3-Acetyl-1-phenylthiourea

In the crystal structure of title compound, C9H10N2OS, there are two symmetry-independent molecules, each having an intramolecular N-H center dot center dot center dot O hydrogen bond generating an S(6) ring motif. The benzene rings and the virtually planar acetylthoiurea fragments [r.m.s. deviations = 0.0045 and 0.0341 angstrom] are oriented at dihedral angles of 50.71 (6) and 62.79 (6)degrees in the two molecules. In the crystal, N-H center dot center dot center dot S and N-H center dot center dot center dot O hydrogen bonds link molecules via cyclic R-2(2)(8) and R-2(2)(12) motifs into a one-dimensional polymeric network extending along [ 101]. The intra-and intermolecular N-H center dot center dot center dot O interactions are part of a three-center hydrogen bond. A-C-H center dot center dot center dot S interaction also occurs.
