Abstract

In the title compound, C12H13N3S, the 4,5-di-hydro-3H-1,2,4-triazole system is nearly planar [maximum deviation = 0.014 (2) Å], while the cyclo-pentane ring adopts a half-chair conformation. The dihedral angle between the mean plane of the 4,5-di-hydro-3H-1,2,4-triazole-3-thione ring and the phenyl ring is 85.49 (14)°, with the S atom 0.046 (1) Å out of the former plane. The crystal structure is stabilized only by van der Waals inter-actions. The investigated crystal was found to be a non-merohedral two-component twin by a 180° rotation about c*, with a refined value of the minor twin fraction of 0.12203 (18).
