Abstract

In the title compound, C17H14N4S, the benzothieno moiety is fused at one end of the pyramidine ring while the triazole ring with a phenyl substituent is fused at the other side. The triazole ring is almost planar [maximum deviation = 0.0028 (3) Å] while the cyclo­hexane ring adopts a half-chair conformation. In the crystal, pairs of inter­molecular C—H⋯N hydrogen bonds form centrosymmetric head-to-head dimers, corresponding to an R 2 2(8) graph-set motif. Further C—H⋯N inter­actions generate a zigzag chain of mol­ecules along the c axis. The supra­molecular assembly is consolidated by π–π stacking inter­actions [centroid–centroid distance = 3.445 (4) Å]
