ACTA CRYSTALLOGRAPHICA SECTION E-CRYSTALLOGRAPHIC COMMUNICATIONS, vol.70, 2014 (ESCI)
The sample of the title compound, C12H15N3S, chosen for study consisted of triclinic crystals twinned by a 180 degrees rotation about the a axis. The five-membered ring adopts a twisted conformation. The dihedral angle between the phenyl ring and the mean plane of the thiourea unit is 78.22 (8)degrees. In the crystal, molecules are linked via pairs of N-H center dot center dot center dot S hydrogen bonds forming inversion dimers.
