✦ Synopsis

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 ÁS hydrogen bonds to form a dimer.

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
