In the title mol­ecule, C24H23N3O3S2, the benzo­thia­diazole ring system is essentially planar, with an r.m.s. deviation of 0.020 (8) Å. The thio­phene and hy­droxy-substitiuted rings form dihedral angles of 23.43 (9) and 35.45 (9)°, respectively, with the benzo­thia­diazole ring system. An intra­molecular O—H...N hydrogen bond is observed. In the crystal, weak C—H...O hydrogen bonds and π–π stacking inter­actions [centroid–centroid distance = 3.880 (3) Å] link mol­ecules into chains along [100]. In addition, there are short S...S contacts [3.532 (3) Å] which link these chains, forming a two-dimensional network parallel to (010).
