(E)-4-[7-(2,3-Dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2,1, 3-benzothiadiazol-4-yl]-2-[(neopentylimino)methyl]phenol

In the title molecule, C₂₄H₂₃N₃O ₃S₂, 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).
