3-Acetyl-1-(2-methylphenyl)thiourea.

In the title compound, C(10)H(12)N(2)OS, the toluene and the N-carbamothio-ylacetamide units are oriented at dihedral angle of 78.75 (5)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked into [101] chains by pairs of N-H⋯S hydrogen bonds [which generate R(2) (2)(8) loops] and pairs of O-H⋯O hydrogen bonds [which generate R(2) (2)(4) loops]. The two motifs alternate in the chain.

3-Acetyl-1-(3-chloro-phen-yl)thio-urea.

In the title compound, C(9)H(9)ClN(2)OS, the 3-chloro-phenyl and acetyl-thio-urea fragments are oriented at a dihedral angle of 62.68 (5)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. Mol-ecules are linked into dimers via a cyclic R(2) (2)(8) motif of N-H⋯S hydrogen bonds. These dimers are further connected through C-H⋯S inter-actions, completing an R(2) (2)(12) motif, into chains along [010].
