| Popis: |
The title crystal structure, C13H16N2S, is a triclinic polymorph of the previously reported orthorhombic structure [Yamin, Kasim & Hamzah (2005). Acta Cryst. E61, o55–o57]. In both structures, the phenyl group is almost perpendicular to the pyrimidine-2-thione ring. In the triclinic structure, inversion-related molecules are linked to form a dimer by N—H⋯S hydrogen bonds, whereas in the orthorhombic polymorph two independent molecules are linked by N—H⋯S hydrogen bonds to form a dimer. |
