(E)-6-Bromo-3-{2-[2-(2-chloro­benzyl­idene)hydrazin­yl]thia­zol-5-yl}-2H-chromen-2-one dimethyl sulfoxide monosolvate

In the title compound C(19)H(11)N(3)O(2)SClBr·C(2)H(6)OS, the mol­ecule adopts an E configuration about the central C=N double bond. The chromene ring system and the thia­zole ring are approximately planar, with maximum deviations of 0.027 (2) and 0.003 (1) Å, respectively. The central thia­zole ring makes dihedral angles of 21.82 (9) and 5.88 (7)° with the chloro-substituted phenyl ring and the chromene ring, respectively. In the crystal, mol­ecules are connected via N—H⋯O, N—H⋯S and C—H⋯O hydrogen bonds, forming supra­molecular chains along the c axis. An intra­molecular C—H⋯O hydrogen bond occurs. π–π inter­actions are observed between the thia­zole and phenyl rings [centroid–centroid distance = 3.6293 (10) Å]. A short Br⋯Cl contact of 3.37 (6) Å also occurs.
