The reaction of cinnamoyl isothiocyanate and aniline gave a the title cyclized thiourea, C 13 H 16 N 2 S. There are two molecules in the asymmetric unit. The pyrimidine-2-thione moiety in each molecule is almost perpendicular to the phenyl group. The molecules are linked by two intermolecular NÐHÁ Á

The title compound, C 15 H 13 N 3 S, was prepared by the reaction of 1-(2-chloroethyl)benzene with hydrazine and phenyl isothiocyanate. Packing is stabilized by N-HÁ Á ÁS intermolecular hydrogen bonds and C-HÁ Á Á interactions.
The title molecule, C 14 H 11 N 3 OS, is non-planar. The phenyl and hydroxyphenyl rings form dihedral angles of 69.08 (9) and 24.57 (9) , respectively, with the ®ve-membered 2,4-dihydro-1,2,4-triazole ring. The molecules form centrosymmetric dimers through NÐHÁ Á ÁS hydrogen bonds, with an NÁ Á ÁS d
In the title molecule, C 15 H 12 ClN 3 S, the dihedral angles made by the substituted phenyl and benzyl rings with the triazole ring are 81.39 (10) and 63.59 (10) , respectively. The crystal structure is stabilized by NÐHÁ Á ÁS, CÐHÁ Á ÁCl and CÐHÁ Á Á% interactions.
