title: 4-Benzyl-3-(thio-phen-2-yl)-4,5-di-hydro-1H-1,2,4-triazole-5-thione.
abstract: In the title compound, C13H11N3S2, the triazole and thio-phene rings are coplanar [dihedral angle = 6.22 (13)°]. By contrast, the phenyl ring is perpendicular to the triazole ring [dihedral angle = 85.58 (13)°], so that the mol-ecule has an L-shape. The thio-phene S atom is syn with the ring imine N atom. In the crystal, eight-membered {⋯HNCS}2 synthons form between centrosymmetrically related mol-ecules, leading to dimeric aggregates that are connected into a supra-molecular layer parallel to (101) by π-π inter-actions between centrosymmetrically related triazole rings [centroid-centroid distance = 3.6091 (15) Å] and C-H⋯π inter-actions.
