4-Benzyl-3-(thio­phen-2-yl)-4,5-di­hydro-1H-1,2,4-triazole-5-thione

In the title compound, C₁₃H₁₁N₃S₂, the triazole and thio­phene 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 mol­ecule has an L-shape. The thio­phene S atom is syn with the ring imine N atom. In the crystal, eight-membered {...HNCS}₂ synthons form between centrosymmetrically related mol­ecules, leading to dimeric aggregates that are connected into a supra­molecular layer parallel to (101) by π–π inter­actions between centrosymmetrically related triazole rings [centroid–centroid distance = 3.6091 (15) Å] and C—H...π inter­actions.
