Abstract

The mol­ecule of the title compound, C16H9ClN2OS, is approximately planar, the dihedral angle between the thia­zolo[3,2-a]benzimidazole ring system and the 4-chloro­phenyl ring being 2.10 (5)°. An intra­molecular C—H⋯S inter­action generates an S(6) ring motif. In the crystal, mol­ecules are stacked into columns along the b axis by π–π inter­actions with centroid–centroid distances of 3.6495 (7)–3.9546 (8) Å.
