چکیده
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).

The title compound, C(13)H(12)N(2)O(2)S, crystallizes with two independent mol-ecules in the asymmetric unit. The two mol-ecules differ in the conformation of the thio-carbonyl and carbonyl groups, and show the typical geometric parameters of substituted thio-urea derivatives. The crystal structure is mainly stabilized by inter-molecular N-H⋯O hydrogen bonding.

In the title compound, C(20)H(26)N(2)OS, four non-H atoms of the thio-urea unit are approximately planar (r.m.s. deviation = 0.005 Å); the phenyl and benzene rings are twisted out of this plane by 28.55 (7) and 60.00 (7)°, respectively. An intra-molecular N-H⋯O hydrogen bond occurs. The hy-droxy group is hydrogen bonded to the double-bond S atom of an inversion-related mol-ecule, generating a h...

In the asymmetric unit of the title compound, C16H17N3O2S, there are two independent mol-ecules (A and B), which show an E conformation with respect to the C=N bond. An intra-molecular O-H⋯N hydrogen bond with an S(6) motif stabilizes the mol-ecular structure. The terminal phenyl and benzene rings are almost orthogonal to each other, the dihedral angle being 87.47 (13)° for mol-ecule A and 89.8...

The title compound, C(28)H(21)N(3)S, crystallizes with two mol-ecules in the asymmetric unit. There are only very slight differences in the torsion angles between the two molecules. The two mol-ecules are stabilized by intra-molecular N-H⋯N inter-actions and the crystal packing is stabilized by inter-molecular N-H⋯S inter-actions.
